18 /* ANSI and traditional C compatibility macros
20 ANSI C is assumed if __STDC__ is #defined.
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 *'
31 DEFUN(name, arglist, args)
33 Defines function NAME.
35 ARGLIST lists the arguments, separated by commas and enclosed in
36 parentheses. ARGLIST becomes the argument list in traditional C.
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'.
43 DEFUN_VOID(name)
45 Defines a function NAME, which takes no arguments.
47 EXFUN(name, prototype)
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)'.
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) { ... }
