In ANSI C it is `NAME PROTOTYPE' (so PROTOTYPE should be enclosed in

For a function that takes no arguments, PROTOTYPE should be `(NOARGS)'. For a function that takes no arguments, PROTOTYPE should be `(void)'.
PARAMS ((args))
We could use the EXFUN macro to handle prototype declarations, but
the name is misleading and the result is ugly. So we just define a
simple macro to handle the parameter lists, as in:
static int foo PARAMS ((int, char));
This produces: `static int foo();' or `static int foo (int, char);'
EXFUN would have done it like this:
static int EXFUN (foo, (int, char));
but the function is not external...and it's hard to visually parse
the function name out of the mess. EXFUN should be considered
obsolete; new code should be written to use PARAMS.
For example: For example:
extern int EXFUN(printf, (CONST char *format DOTS)); extern int printf PARAMS ((CONST char *format DOTS));
int DEFUN(fprintf, (stream, format), int DEFUN(fprintf, (stream, format),
FILE *stream AND CONST char *format DOTS) { ... } FILE *stream AND CONST char *format DOTS) { ... }
