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) { ... } | |
