1.1     ! root        1: C-Language Header Files for MS OS/2
        !             2: ===================================
        !             3: 
        !             4: The MS OS/2 C-language header files contain the definitions you need to
        !             5: use the functions, data types, structures, and constants described in the
        !             6: Microsoft Operating System/2 Programmer's Reference. 
        !             7: 
        !             8: When you include the OS2.H file, the C preprocessor automatically defines
        !             9: many, but not all, of the most commonly used MS OS/2 functions. The OS2.H
        !            10: header file is the first file of a set of files that contains the MS OS/2
        !            11: function definitions. Each file contains definitions for the functions,
        !            12: data types, structures, and constants associated with a specific group of
        !            13: MS OS/2 functions. To minimize the time required to process the many
        !            14: header files, each function group is conditionally processed depending on
        !            15: whether a corresponding constant is defined within the program source
        !            16: file. The following is a list of these constants with descriptions of the
        !            17: function groups they represent: 
        !            18:

        !            44: 
        !            45: To use a function within your program function, you simply define the
        !            46: corresponding constant by using the #define directive before including the

        !            51: C-Language Library Files for MS OS/2
        !            52: ====================================
        !            53: 
        !            54: The MS OS/2 C-language Run-Time Libraries contain the necessary code to
        !            55: make your C program an OS/2 executable, including run-time routines such
        !            56: as "printf()" which you may have used in your program. The example
        !            57: programs in this toolkit assume that you have Microsoft C 5.10 and that
        !            58: you have run its SETUP program to install libraries for MS-DOS (real-mode)
        !            59: as well as MS OS/2 (protected-mode).  If you have done this, you will have
        !            60: run-time libraries named SLIBCEP.LIB, LLIBCEP.LIB, etc.  This is what this
        !            61: toolkit expects.  If you have told MS C 5.10 SETUP that you wish to write
        !            62: only Protected Mode programs, it will have created the protected mode
        !            63: libraries (required by this toolkit) using the names SLIBCE.LIB, LLIBCE.LIB,
        !            64: etc., instead of SLIBCEP.LIB, LLIBCEP.LIB, etc.  In this case, you will have
        !            65: to rename those libraries from SLIBCE.LIB to SLIBCEP.LIB, etc. in order for
        !            66: the makefiles in this toolkit to work.
