- language identifier
- A 16-bit value that identifies a language and, where appropriate, the variant of the language being used. A language identifier is a combination of a primary language identifier and a sublanguage identifier. For example, if the primary language identifier specifies English, the sublanguage identifier might specify Australian English.
- last-chance notification
- The last time the system notifies the debugger of an exception. If the debugger does not handle an exception after last-chance notification, the system terminates the process being debugged. See also debugger, process.
- last-error code
- A per-thread value set by Win32 functions when an error occurs. The last-error code can be retrieved by using the GetLastError function.
- LCID
- See locale identifier.
- LCN
- Logical cluster number. See logical cluster.
- license server
- The part of a license system that runs on a file or applications server.
- line
- A set of highlighted pixels on a video display (or a series of dots on a printed page) that is defined by two points: a starting point and an ending point. See also pixel.
- line and curve attributes
- The width, color, style, and (in the case of lines or curves drawn with a geometric pen) end cap, join style, and transformation of a line or curve. See also end cap, geometric pen, join style, transformation.
- list box
- A control window that contains a list of items that can be selected by the user.
- load-time linking
- Dynamic linking that occurs when a program (either an application or a dynamic-link library [DLL]) makes an explicit call to a DLL function. This requires that the executable module of the program be built by linking with the DLL's import library. When the program is executed, the operating system uses the information provided by the import library to locate the executable module of the DLL, which is mapped into the address space of the process. See also import library, process.
- local atom
- An atom stored in an application's atom table. The value of a local atom is unique within the application but may not be unique throughout the operating system. See also atom, atom table.
- local atom table
- See atom table.
- locale identifier (LCID)
- A value containing the language identifier in the lower word and a reserved value in the upper word. The identifier supplied in an LCID is a standard international numeric abbreviation. This LCID has the components necessary to uniquely identify one of the installed system-defined locales.
- logfile
- A configuration registry key that specifies the filename of an event log. Logfiles are subkeys of the EventLog registration key. See also key, subkey.
- logging off
- The action of stopping all processes running in the security context of the process that called the Exit function.
- logical brush
- A description of a bitmap. A logical brush can be selected into a device context. See also bitmap, device context.
- logical cluster
- One of the clusters of a file for which the clusters are in the order in which they are found on the hard drive. Logical clusters are distinguished from virtual clusters. See also virtual cluster.
- logical coordinate space
- Another name for the world or page coordinate space. If an application has set a world-space to page-space transformation, the logical space is the world space; otherwise, the logical space is the page space.
- logical palette
- An array of colors, or "color palette," that an application creates and associates with a device context and uses for graphics output. See also device context.
- logical volume
- See partition.
- long filemark
- A filemark that contains a long erase gap that enables an application to position the tape at the beginning of the filemark and to overwrite the filemark and the erase gap. See also erase gap.
