L:

L2CAP: The Bluetooth Logical Link Control And Adaptation Protocol (L2CAP). It controls how multiple users of the link are multiplexed together, handles packet segmentation and reassembly, and conveys quality of service information.
L function: In the context of Symbian C++ programming, a function with a trailing L in its name, e.g. NewL(): such functions may leave, either directly by calling User::Leave(), or indirectly by calling other functions that may leave.; See also: leave
label: A descriptor which contains the name of a contact item field, for instance First name or Home address.; See also: descriptor field
label margin: Margin used for labels, normally used for paragraph style.; See also: view rectangle line cursor margin
LAF: A Look and Feel software module provided by phone manufacturers to customise devices and user interfaces. For example, the scroll bar appearance.
landscape: Horizontal page orientation for printing.; See also: orientation portrait
Language downgrade path: An array of up to eight languages which are used in turn to find the best matching language-specific version of a language-neutral filename. The first language in the path is the language of the current locale. Up to the next three (at indices 1, 2 and 3) can be customised. The remaining languages in the downgrade path are based on a table of language near equivalence which is internal to Symbian.
language extension procedure: An OPX procedure written in C++ that can be called from an OPL program.; See also: OPX OXH
large bitmap: A FBS bitmap whose size is greater than a certain threshold value, currently set at 4Kb.; See also: small bitmap
latchable: Buttons that can latch change their state when pressed and stay in that state until changed again by the user.
latching command button: A command button that remains depressed when the pointer is removed from it.; See also: command button
latency: The time taken between the occurrence of an event and the response to it.
latitude editor: A concrete control that supports editing a latitude value.
layout co-ordinate: x,y co-ordinates whose origin is the top left hand corner of the text area.; See also: text area window co-ordinate
layout engine: The Symbian OS text layout engine lays out editable text in a window.; See also: editable text
layout object: Represents necessary interface between document and view.; See also: text object
LDD: A logical device driver. Typically, a single LDD provides functionality common to a class of hardware devices, whereas a PDD supports a specific member of that class.; See also: PDD
leave: To leave, is to invoke the function User::Leave(). This causes a return to the current trap harness. A function may also leave because a function it called left.; See also: trap harness cleanup stack
left adjust: The number of pixels to move before displaying a character.; See also: right adjust
left text margin: The distance between the leftmost extent of a paragraph and the left edge of the text area. An increasing left text margin width causes a scroll right to occur (text moves leftwards) and a decreasing left text margin width causes a scroll left to occur (text moves rightwards). For an illustration of the left text margin, see Screen layout.; See also: text area paragraph
length: The length of data currently represented by a descriptor.
line: Text Views : A line of text as seen on the view. A line is a member of just one paragraph. One paragraph may consist of many lines. Lines only apply to text that has been formatted. ETel : A physical line from which calls are made.; See also: line capabilities phone call paragraph formatted band
line capabilities: Indicates the functionality supported by a line, as encapsulated by the Telephony Server, such as connecting to data, voice or fax calls; detecting the hook and line status, and creating calls.; See also: line
line cursor: Indicator in line cursor margin, used to indicate which line the cursor is on.; See also: line cursor margin cursor
line cursor margin: Margin used for line cursor.; See also: view rectangle label margin line cursor
line primitive: A graphics operation to draw, (using the pen), a line or sequence of lines.; See also: pen polyline graphics operation
line status: In the context of ETel, the current status of calls on the line, e.g. dialling.
linear address: Alternative name for virtual address, the name 'linear' is historical. 'Virtual' is preferred.
list: Objects or data items connected together to form a meaningful sequence. Also known as a 'queue'.
local file system: A file system which mediates access to any devices local (non-removable) to the machine.; See also: file system
local time: See home time; See also: universal time home time
location area code: This specifies the general location, similar to an STD code for mobile numbers.
long network name: Networks have both short and long names. The long name is used in preference. In Symbian OS, the long name is 16 characters.; See also: short network name
longitude editor: A concrete control which supports editing a longitude value.
low water mark: When this point is reached in a receive buffer, a flow control resume event is triggered.; See also: XON
