| 18 | /* ANSI and traditional C compatibility macros | |
| 19 | ||
| 20 | ANSI C is assumed if __STDC__ is #defined. | |
| 21 | ||
| 22 | Macros | |
| 23 | PTR - Generic pointer type | |
| 24 | LONG_DOUBLE - `long double' type | |
| 25 | CONST - `const' keyword | |
| 26 | VOLATILE - `volatile' keyword | |
| 27 | SIGNED - `signed' keyword | |
| 28 | PTRCONST - Generic const pointer (void *const) | |
| 29 | ||
| 30 | EXFUN(name, prototype) - declare external function NAME | |
| 31 | with prototype PROTOTYPE | |
| 32 | DEFUN(name, arglist, args) - define function NAME with | |
| 33 | args ARGLIST of types in ARGS | |
| 34 | DEFUN_VOID(name) - define function NAME with no args | |
| 35 | AND - argument separator for ARGS | |
| 36 | NOARGS - null arglist | |
| 37 | DOTS - `...' in args | |
| 38 | ||
| 39 | For example: | |
| 40 | extern int EXFUN(printf, (CONST char *format DOTS)); | |
| 41 | int DEFUN(fprintf, (stream, format), | |
| 42 | FILE *stream AND CONST char *format DOTS) { ... } | |
| 43 | void DEFUN_VOID(abort) { ... } | |
