| 22 : | Macro ANSI C definition Traditional C definition | ||
| 23 : | ----- ---- - ---------- ----------- - ---------- | ||
| 24 : | PTR `void *' `char *' | ||
| 25 : | LONG_DOUBLE `long double' `double' | ||
| 26 : | CONST `const' `' | ||
| 27 : | VOLATILE `volatile' `' | ||
| 28 : | SIGNED `signed' `' | ||
| 29 : | PTRCONST `void *const' `char *' | ||
| 30 : | |||
| 31 : | DEFUN(name, arglist, args) | ||
| 32 : | |||
| 33 : | Defines function NAME. | ||
| 34 : | |||
| 35 : | ARGLIST lists the arguments, separated by commas and enclosed in | ||
| 36 : | parentheses. ARGLIST becomes the argument list in traditional C. | ||
| 37 : | |||
| 38 : | ARGS list the arguments with their types. It becomes a prototype in | ||
| 39 : | ANSI C, and the type declarations in traditional C. Arguments should | ||
| 40 : | be separated with `AND'. For functions with a variable number of | ||
| 41 : | arguments, the last thing listed should be `DOTS'. | ||
| 42 : | |||
| 43 : | DEFUN_VOID(name) | ||
| 44 : | |||
| 45 : | Defines a function NAME, which takes no arguments. | ||
| 46 : | |||
| 47 : | EXFUN(name, prototype) | ||
| 48 : | |||
| 49 : | Is used in an external function declaration. | ||
| 50 : | In ANSI C it is `NAMEPROTOTYPE' (so PROTOTYPE should be enclosed in | ||
| 51 : | parentheses). In traditional C it is `NAME()'. | ||
| 52 : | For a function that takes no arguments, PROTOTYPE should be `(NOARGS)'. | ||
| 53 : | |||
| 54 : | For example: | ||
| 55 : | extern int EXFUN(printf, (CONST char *format DOTS)); | ||
| 56 : | int DEFUN(fprintf, (stream, format), | ||
| 57 : | FILE *stream AND CONST char *format DOTS) { ... } | ||
| 58 : | void DEFUN_VOID(abort) { ... } | ||
