Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

─────C/C++ Compiler─────────────────────────────────────────────────────────
 
     Both the name of libraries, in general, and the name of the default
     library──the name that the compiler embeds in an object file──are
     determined by the following variables:
 
        ■ Memory model that the library supports
 
        ■ Link mode that the library supports
 
        ■ Language that the library supports
 
        ■ Math model that the library supports
 
        ■ Operating-system mode that the library supports
 
     The following table shows the individual components of a library
     name and the order in which the components occur in the name of the
     final library.

     Memory Model
 
     S    Tiny or small
     M    Medium
     C    Compact
     L    Large or huge
 
     Link Mode
 
     LIB  Static linking (linking that occurs at link time)
     DLL  Dynamic linking (linking that occurs at run time)
 
     Language
 
     C    The C programming language
 
     Math Model
 
     A    Fast alternate math
     E    Inline emulation or emulation calls
     7    Inline 80x87 or 80x87 calls
 
     Operating-System Mode
 
     R    Real mode (DOS)
     W    Windows
     WQ   QuickWin
 
     Examples
 
     SLIBCEW     Small memory model, static linking, C programming
                 language, inline emulation or emulation calls,
                 Windows.
 
     LLIBC7R     Large memory model, static linking, C programming
                 language, inline 80x87 or 80x87 calls, real mode.
 
     Exceptions
 
        ■ QuickWin libraries (WQ) do not support dynamic linking.
 
        ■ Due to the Windows math implementation, the "7" component
          is not necessary for Windows libraries. Windows libraries
          support only the A and E math models.
 
        ■ For compatibility with previous versions of Microsoft C,
          LLIBCDLL.LIB does not comply with the C/C++ library naming
          scheme.
