Guest prayaas1998 Posted December 14, 2011 Report Share Posted December 14, 2011 A abld.bat batch file Controls all aspects of building a project in the SBSv1 build system. It is created in the current directory by the bldmake tool from a component description file. abstract Used to describe a class which describes behaviour, but which does not implement it. Many implementations of the behaviour might be available. Each is referred to as a concrete class. access count A record of the number of objects referencing a contact item. A contact item cannot be fully deleted until its access count is zero. access mode The locking specified when opening a file: exclusive, readers only, or shared with any. active object A class derived from CActive, which is responsible for issuing requests to asynchronous service providers and handling those requests on completion. active scheduler A class derived from CActiveScheduler, responsible for scheduling events to the active objects in an event-handling program. address For Bluetooth, each Bluetooth device has built into its hardware a 48-bit device unique address. agent In the context of the Network Interface Manager (NifMan), the component which NifMan uses to set up a connection. Or, in the context of a vCard, a property within a vCard whose value is a string representing another entity. alarm due time The time that the alarm was/is due. Before an alarm activates, this is the same as the alarm time. If the alarm is snoozed, then the due time remains the same, but the alarm time becomes the new activation time. alarm message The message which is displayed to the user when the alarm time is reached. alarm sound An algorithmic sound or a sampled sound file stored in the system alarms directory (\System\Alarms). alarm time The time the alarm is next expected to activate. Alaw A standard for encoding 12-bit sound as 8-bit data. Aleppo Legacy help authoring tool. algorithmic sound A sound generated by the sound driver by synthesising sounds according to an algorithm. Alpha blending The term used where a value (called 'Alpha' ) is used to indicate a transparency value for a pixel. If the Alpha=maximum then the pixel is opaque, that is the full colour of the pixel is written to the destination. If Alpha=0 then the pixel is fully transparent, and the destination is left unaltered. Values in-between cause 'blending' with the formula Destination = Source*Alpha/max_Alpha + Destination*(max_Alpha-Alpha)/max_Alpha anchor Marks the start of a selection API Application Programming Interface, the visible public behaviour a system object or component exposes to other objects or components. app UI A control environment class which defines application-wide aspects of the user interface, such as key event handling. Each application that uses the control environment has exactly one app UI. or The interface an application presents to the user, or the subclass of CEikAppUi an application uses. application A program that provides a graphical user interface to the user; applications are created using the application framework which provides standard means for applications to receive input events and manage data (documents). application capabilities Set of properties for an application that are understood by the application architecture, such as its support for embeddability, and whether it is hidden. They are set in the application registration file provided with the application.This concept should not be confused with a program's security capabilities. ABI Application Binary Interface. This is a standard for the interfaces of binary code running in ARM environments, and is intended to allow inter-operation of binaries produced by different compilers that conform to the standard. The specification is published by ARM. application program A program made up of a number of classes. It usually consists of a user interface and an application engine. application resource file A resource file written by an application programmer as part of the application source; such files are used to define the application user interface, and to define literal strings and other constant data. application view A window managed by an application, which typically displays user data. archive A file attribute indicating whether it has been saved since changes were made to it. The archive attribute is assigned to a file when it is created, replaced or written to. ARM processors A processor with 16/32 bit embedded RISC from ARM. array buffer An area containing the elements, or pointers to the elements of an array. array capacity The number of elements which an array can hold or represent within the space currently allocated to its array buffer. array granularity The number of elements by which the array capacity of an array is increased. ascent The ascent of a character cell defines the position of the baseline within every character cell of a font. It is the number of pixels from the top of the cell to the baseline. The baseline is not a pixel row itself, but occurs between two pixel rows. App UI The central user interface class. It creates and owns controls to display the application data, and centralises handling of command input from standard controls such as menus and toolbars. application class Defines the properties of the application, such as UID and caption, and creates a new document. application framework Handles application start-up and accessing the application data (its document). application framework API The frameworks that define the application structure and their basic user interface handling. associated window The window associated with a control. If the control is a window-owning control, this is the window is owns. If the control is non-window-owning, it is the window in which the control is displayed, i.e., the window owned by the nearest window-owning-control above it in the run-time control hierarchy. argument A value on which a function operates. ASIC Application Specific Integrated Circuit ASSP Application-Specific Standard Product. An integrated off-the-shelf part consisting of CPU, MMU, cache and a number of on-chip peripherals (typically UART's, timers, LCD controller). Designed and marketed by a silicon vendor and intended to be used in a class of devices. asynchronous request A request for an asynchronous service from an asynchronous service provider. asynchronous service provider A system, component or class which provides a service asynchronously Requests are indicated by function calls with a TRequestStatus reference parameter. AT+FCR=1 Class 2 modem receive command. attribute A characteristic of a file or directory. Attributes determine the visibility of files and directories and whether or not they can be deleted or modified. Attributes include hidden, read-only and archive. For Bluetooth, a Bluetooth service is described by a service record, consisting of a list of service attributes. Each attribute has an ID, a type, and a value. audio streaming Playing audio data incrementally, as the data fragments are received by the client, rather than waiting until the entire sound clip has downloaded before playing it. automatic transaction A transaction which is operated automatically by a database, if no explicit transaction is begun when modifying the database. auto-repeat Repeated key events generated by the window server when a user holds down a key Avkon S60 extensions and modifications to Uikon and other parts of the Symbian OS application framework.

DCE Data communication equipment (e.g. modem). DCN Disconnect. This command indicates the initiation of fax modem phase E — call release. This command requires no response. default country The default country is used as the default country to dial to. default display time The time at which, by default, agenda entries are displayed in views. default document file The document file in which a file-based application saves data if no filename is given by the user. default document file name The name of an application's default document file. default owning window group If a window group is closed while it has the keyboard focus, this window group receives the focus, unless the closed window group had called SetOwningWindowGroup(). A window group becomes the default owning window group by calling RWindowGroup: efaultOwningWindow(). default screen device A screen device created by CCoeEnv when it is constructed. Typically used as the standard screen device for this application. default session path The default path for the current file server session. It is set to the connecting process’s private directory. deferred loading The loading into memory of pictures inserted in a rich text object only when they are required to be displayed. The purpose is to reduce the time taken to retrieve a text object and to save memory usage. descriptor A class derived from TDesC, which describes an area of memory used as either a string or some binary data. device File Server : a hardware and software interface which may be associated with a volume, and which has one of the letters A through Z assigned to it. device area The area of the graphics device to which drawing can be done, (if no smaller clipping region is set in a window graphics context). device password dialog Dialogs that allow the user to enter or change the device password.

May be "scheduled" by ISRs to perform services for them. DFRD Device Family Reference Design. All products from the same DFRD are able to run the same third party software, content and services. From v7.0 onwards, this term is no longer used. dialog A control, normally invoked by the selection of a menu command, allowing interaction between the user and the program. digital certificate An electronic message attachment that is used for security purposes. The most common use of a digital certificate is to verify that a user sending a message is who they claim to be, and to provide the receiver with the means to encode a reply. digital signature A digital code that can be attached to an electronically transmitted message that uniquely identifies the sender. direct file store A file based persistent store in which streams can be created and objects externalised to them but, once committed and closed, they cannot subsequently be changed. Direct Navigational Link (DNL) Applications that use the view architecture can allow other applications to send messages specifying a view to display, and possibly relevant accompanying data, called a Direct Navigational Link (DNL) message. The ability to request views and send DNLs is provided by the UI Control Framework API's CCoeAppUi class. directory Structure containing information on files and subdirectories. directory entry Holds information about a file or a directory owned by the directory that contains the entry. direct screen access A way of drawing to the screen without using the window server. As this avoids client-server communication, it is much faster. DIS Digital Identification Signal. Frame containing the capabilities of the called fax. displayable window A window that can be displayed on the screen. In practice, this means all concrete window classes except window groups. dithering Error diffusion, or dithering, is a way of avoiding aliasing due to a cut-down palette size. If a colour cannot be matched exactly then the nearest colour is used and the difference remembered. Then on the next pixel the difference is added to the desired colour and the result matched to the nearest colour available. In this way a mid-blue, for example, might be represented by a scattering of dark blue and light blue, if that mid-blue were not available in the current palette. DLL Dynamic Link Library. Dynamic Link Libraries are loaded in response to an explicit API call made by an executing program. DLL export table An area in the DLL which lists the DLL addresses of exported items; In Symbian OS, these items are indexed by ordinal. document Application Architecture : A run-time object containing data associated with a specific instance of an application program. A document may be stored to and restored from a document file. Application framework : File-based applications use a document object to provide an intermediate layer between the app UI, the model and the file the model will be stored in. Non-file-based applications will only use a document to create the application's UI. document class Represents the data model for the application. In file-based applications, it stores and restores the application's data. It handles requests to edit a document by creating an app UI. document file A file that is the externalised form of a main document and any embedded documents it contains. document head stream A stream directly accessible from the root stream dictionary. document position A reference to a position in an editable text object. It is an integer ranging from zero (start of document), to the length of document. Depending on the context, a document position either refers to the character indexed by this number, or the point between this character and its predecessor (if any). door The Symbian OS document embedding mechanism. A door represents an embedded document. There are two types of door: glass doors and iconic doors. down event A Window Server event of type Button1Down, Button2Down or Button3Down. The user actions that result in these events will vary depending on the type of pointing device: mouse, pen, etc. drag event An event corresponding to a user's dragging a draggable control. drawing mode Determines the logical operation used to put pen or brush colour onto the graphics device. Defined in a graphics context. drive The letter used to identify one device or volume accessed through the File Server. drive list The list of volumes that are currently valid. drive name selector A type of choice list which allows a drive to be selected from those currently available.

The command response to the capabilities identified by the DIS signal. DTE Data terminal equipment (e.g. computer). DTMF Dual Tone Multi Frequency (touch tone). A method used by the telephone system to communicate the keys pressed when dialling. Pressing a key on a phone's keypad generates two simultaneous tones, one for the row and one for the column. These are decoded by the exchange to determine which key was pressed. DTR Data Terminal Ready. An RS232 output line that can be held high to indicate that a device serial port is active. DUNP The Bluetooth Dial-Up Networking Profile. It allows a computer to use a Bluetooth cellular phone or modem to make and receive data calls. duration editor A control which supports editing a duration value. dynamic buffer A buffer, derived from CBufBase, used to hold data is of significantly varying length, which can be extended when necessary. dynamic link library A library containing functions that are linked and stored separately from the programs that use them. dynamically loaded DLL A DLL loaded by another program using RLibrary::Load().

Each Index entry (and so each item) is uniquely identified by an ID field. entry ID Uniquely identifies an agenda entry in an agenda file. Unlike the unique ID, the entry ID can change if the entry is updated, or if another entry is deleted from or added to the file. It therefore cannot be used to identify the entry during synchronisation. entry observer A class implemented by a messaging client that is notified when the data representing an individual entry changes, or when requested access to a message store has been successfully gained. entry point In Symbian OS before v9, a function E32Dll() that was called when a DLL was loaded, or attached by a thread or process. entry symbol The character which is used to represent an entry in Agenda application views.

ODR Acronym for the One Definition Rule. OMA Open Mobile Alliance. An alliance which facilitates usage of mobile data services. It delivers specifications for mobile application .technology, targeting at promoting interoperability. One Definition Rule One Definition Rule: No translation unit (in an application including all its DLLs, statically linked or dynamically loaded) shall contain more than one definition of any variable, function, class type, enumeration type or template. A consequence of the One Definition Rule, is that all objects (including variables and functions) that semantically refer to the same C++ object map onto the same address in object code. For example, say we have the function, inline int getCounter { static int iCounter = 0; return iCounter++ ; }. If the One Definition Rule holds, all instances of this in-lined function in an application, including all its dependant binaries (statically linked or dynamically loaded) will access the same static variable iCounter. Note that in Symbian OS as in Microsoft Windows, the One Definition Rule does not hold; whereas on Unix and Linux the One Definition Rule does hold. on event An event generated by the window server when the machine is switched on.

A group of option buttons may be used to toggle mutually exclusive application states. OPL Organiser Programming Language. An open source BASIC-like language that can be used for rapid application development. OPX An OPL extension DLL providing language extension procedures. ordinal A number which identifies a column in a particular column set or rowset. ordinal build A build which produces a DLL export table that indexes functions by ordinal. ordinal position The position of a window in the z-order, i.e. from front to back on the screen. The front-most window (the window in the foreground) has an ordinal position of 0. orientation Whether page is vertically or horizontally aligned. origin The top-left corner of a control. orphan (1) an object which cannot be accessed either as a local automatic variable, a global variable, via a pointer or as the result of any function call; (2) to create such an object Orphaned objects are undesirable as they use unrecoverable system resources. There are two types of orphaned object: objects orphaned on the stack and objects orphaned on the heap. Orphans can be created through program errors, or by a function leaving. It does not matter if T objects are orphaned on the stack. All other orphans are undesirable and, in the case of leave processing, it is essential to ensure that cleanup code handles objects that would otherwise be orphaned. orphan alarm When a session with the alarm server closes the connection it can orphan the alarm. This alarm will be serviced after the session closes. An orphan alarm has no session owner and no session is notified when the alarm is due. OTA Over-The-Air. Term used for Firmware updates. out of line An agenda entry may be stored inline or out of line. Out of line means that the entry's rich text object is stored in an embedded store in the entry's stream. An agenda entry is set to be stored out of line if its rich text object is large. own card A contact item containing information about the device's owner. This can be sent to another compatible electronic device as a vCard. owning service The messaging service that is the ultimate parent of an entry. owning window group If a window group is closed while it has the keyboard focus, its owning window group receives the focus. This will be the default owning window group, unless the window group has called SetOwningWindowGroup().

Guest prayaas1998 Posted December 14, 2011 Report Share Posted December 14, 2011 P package file Makesis project file type, which has the extension pkg. PAD Packet Assembler/Disassembler. Allows access to a packet data network from a circuit-switched network. page specification The page orientation and page size for printing encapsulated by the TPageSpec class. panic An operation to terminate a thread that has caused an error. Panics are used when the error is due to incorrect program code, such as passing an illegal parameter value. paragraph A sequence of one or more words terminated by a paragraph delimiter. paragraph delimiter Marks the end of a paragraph. In rich text, the paragraph delimiter may be regarded as storing the paragraph format attributes for the paragraph that it terminates. This means that when a paragraph delimiter is deleted, the paragraph formatting for that paragraph is set to the paragraph formatting of the paragraph into which it is merged. paragraph fill colour The colour setting used to fill a paragraph. May also fill the left text margin, if one has been set. paragraph format attribute Describes the appearance of paragraphs; for instance margin width, text alignment, bullets and paragraph spacing. paragraph format layer A format layer specifying paragraph format attributes. parent A Message Server entry that owns another entry: for example, a folder is the parent of a message within it. partition An area of a media that can be used as a single device and, if formatted, as a volume. password mode Window server mode where the user is required to enter a password before any further actions can be performed. path The identification of a file or directory by its components. The components are drive, directory components, filename and extension. PC Synchronisation Connecting a Symbian phone to a PC and synchronising the data store, for example, email, PC based contacts, diary, and other applications. PCconnectivity A possibility to connect the device to a personal computer and use this connection (e.g. via a cable) to transfer information. PCI Peripheral Component Interconnect. A standard for connecting peripherals to processors that is processor independent. PCM (Pulse Code Modulation) The process of taking samples of an analog sound and storing the results as binary data. PDD A physical device driver. A PDD provides functionality specific to a particular device. PDE Page Directory Entry. In an MMU with two level page table, this term is used for the 32 bit entry in the first level table, or page directory. Each PDE maps 1M on ARM, 4M on X86. PDU message The PDU message format describes a generic SMS message as a byte stream. PE Portable Executable - a standard format for executable (image) files and object files. The PETRAN tool converts executables from PE format to the Symbian OS executable format. pen The pen is used for free line and shape outline drawing. The pen colour also affects text colour. pen attribute Pen attributes are: pen colour, pen style, pen width. pen colour The colour in which the pen draws lines and text. pen style The style with which the pen draws lines. This may be null, solid, dotted/dashed. pen width The width in pixels that the pen draws lines. permanent file store A file based persistent store in which streams can be created and subsequently re-opened and changed. persistent store A store whose streams have a longer lifetime than the applications that created them. phone A physical object which connects to a line. phone capability Ability to support fax and modem protocols. May include: fax interface supported, ability to transmit voice, modem detection events supported, ability to steal comms port. phone indicator An indicator showing some status information for the phone. Indicator types are defined in TIndicatorType. phone mode Phone operational state; idle, establishing line, online data and online command. phone status The mode of operation and modem connection status for the phone. physical address A 'real' address, the value that must be placed on the system address bus to select a physical memory bank or device. picture Text Content : A graphic inserted into a rich text object. Pictures are type extensible. Graphics Device Interface (GDI) - Basic Graphics Functions : An object with an original size in twips, that can be stored, restored, and drawn to any graphics context. Concrete picture classes draw in different ways and allow cropping and scaling. Pictures are the basis for doors. picture character Represents a picture. picture header Identifies a picture type. A picture occupies a single character position. The picture header is stored in the same stream as the text. The picture is stored in a different stream to support deferred loading. When inserting a picture into rich text, the picture header rather than the picture itself is inserted into the text. picture header factory Produces picture headers of a single type. Required because pictures are type-extensible. PIM Personal Information Managers, for instance agenda and contacts applications. PIN2 A personal identification number which provides access to protected areas of the SIM e.g. barred phone books. P.I.P.S. An API layer, above the Symbian OS native APIs, that is more closely aligned with standard C and POSIX APIs, making Symbian software development more accessible to developers who program using the C language. pixel A single display element for a graphics device (screen). pkg file Makesis project file extension. plain text Provides storage for text and services to manipulate it but does not support format attributes and cannot be displayed. PLMN Public Land Mobile Network. Another name for a GSM phone network. plug-in A polymorphic interface DLL used to enhance, or extend the operation of a framework. point A point specified in terms of (x,y) co-ordinates point primitive A graphics operation to draw (using the pen) a single point. pointer cursor The cursor that indicates the current position of the pointer (different from the text cursor and line cursor). pointer event A pointer-related event such as up, down, drag, move. pointer grab When the pointer is grabbed by a window, all events are sent to that window, regardless of which window they occurred in. policy The way an application works is its policy. Policy imposes constraints which on the one hand limit freedom of design and implementation, and on the other hand make it easier to design and implement if the policy is followed. policy-free A user interface or programming system is policy-free if it imposes little or no policy. polling Polling is the fax mode of operation where the caller requests the remote answering machine to send a fax. polyline A concatenated sequence of straight lines. polymorphic DLL A DLL that provides some plug-in functionality to another program by implementing a pre-defined interface. They are dynamically loaded by the DLL user during run-time. In Symbian OS, the typical use of a polymorphic DLL is to implement a framework extension. Polymorphic DLLs are sometimes known as provider DLLs. polymorphic interface DLL Polymorphic DLL POP3 Post Office Protocol version 3: a common protocol for transferring mail from the server ('Post Office') to the client. Defined in RFC 1939. portrait Vertical page orientation used for printing. POSIX Portable Operating System Interface, standards specified by the IEEE that define the API for software compatible with variants of the Unix operating system. POTS Plain Old Telephone Service: a basic telephony service that offers only the ability to place and receive calls. PPP The Point-to-Point Protocol, an IETF standard, which manage the dial-up link. preferred networks list Priority list for selection of a preferred network. pre-processor Prepares source files for further processing, used in C++ to replace macro representations with the code to be compiled. primary The first executable in the ROM to run, namely the kernel. primary base class A base class which is not an interface class. Usually, derived from CBase. primary inheritance tree The inheritance tree formed by primary base classes. By the rules of interface class use, multiple inheritance may never be used to form an inheritance graph that is more complex than a tree with a single root. print parameter Number of copies and page range to print. printer device A graphics device that is used for printing. printer model UID and associated name of a printer. printer model list The list of supported printer models. priority client ETel priority clients have privilege in call manipulation functions. For instance, the priority client can hang up or put on hold other clients calls. If another client has a data call active, and the priority client suddenly needs to make an emergency call, it can force the other call to be dropped by making that request. priority function ETel priority functions are executed using pre-allocated memory, and hence cannot fail with an out of memory error. Any client can use a priority function, not just the priority client. process The Symbian OS unit of memory protection - one user process may not access another's memory. A process contains one or more threads. process-relative A handle is process-relative if ownership of that handle is vested in the process. product A combination of CPU core, ASSP and surrounding development board.

PSTN Public-switched Telephone network. public/private key pair A public key known to everyone and a private key that is known only to the recipient of the message. When someone wants to send a secure message to another person, they use their public key to encrypt a message. The receiver then uses their private key to decrypt it. PTE Page Table Entry. In an MMU with two level page table, this term is used for the 32 bit entry in the second level table, or page table. Each PTE maps 4K on ARM and 4K on X86.
