- Microcomputer C header files assumptions
- ========================================
-
- To avoid having my C programs looking like a tangle of macroes
- and ifdefs, I've started canonizing the header files for the
- different C compilers I use. My starting point is the draft ANSI
- C standard, with generous influence from Borlands Turbo-C 2.0
- and Microsoft C 5.1.
-
- Below is what my programs assume about the standard header files.
- If your compiler has trouble compiling a program written or
- supported by me, the assumptions below should help you a long way
- towards successful compilation.
-
- (( If you don't want to hack the standard headers supplied with
- your compiler, you may create an extra header named "gh.h" or
- something, put everything in it, and include that. ))
-
-
- DOS.H
- =====
-
- * There should exist a header named dos.h, which should contain
- macro definitions, function declarations and type definitions
- for the operating system functions.
-
- * Dos.h is supplied with Turbo C and Microsoft C. AZTEC users
- should copy (or rename) IO.H to DOS.H.
-
- * Dos.h should define symbolic names for the file system
- attribute flags.
-
- For MS-DOS, this should look like:
-
- #ifdef __MSDOS__
- #define _A_NORMAL 0x00 /* Normal (r/w) file */
- #define _A_RDONLY 0x01 /* Read only attribute */
- #define _A_HIDDEN 0x02 /* Hidden file */
- #define _A_SYSTEM 0x04 /* System file */
- #define _A_LABEL 0x08 /* Volume label */
- #define _A_DIREC 0x10 /* Directory */
- #define _A_ARCH 0x20 /* Archive */
- #endif
-
-
- STDIO.H
- =======
-
- * Stdio.h should define symbolic names for standard file
- descriptors (see ref. 1, sec. 8.1, p. 160) as follows:
-
- #define STDIN (0)
- #define STDOUT (1)
- #define STDERR (2)
