arguments, the last thing listed should be `DOTS'.
- DEFUN_VOID (name)

Defines a function NAME, which takes no arguments.

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
the function name out of the mess. EXFUN should be considered
obsolete; new code should be written to use PARAMS.
- For example:
- extern int printf PARAMS ((CONST char *format DOTS));
- int DEFUN(fprintf, (stream, format),
- FILE *stream AND CONST char *format DOTS) { ... }
- void DEFUN_VOID(abort) { ... }
+ DOTS is also obsolete.
+
+ Examples:
+
+ extern int printf PARAMS ((const char *format, ...));
