Microsoft C is the standard tool of the professional programmer and this is the official run-time library documentation reference to the latest version. The book provides detailed information on more than 500 C run-time library functions and macros, including rules and procedures. This updated edition is aimed at the users of Microsoft QuickC (both the DOS and Windows versions), who are using the run-time library but have no library documentation. Of particular note is the information on compatibility with ANSI C, MS-DOS, OS/2, UNIX and XENIX.
