#include <varargs.h> function(va_alist) va_dcl
Description
To use the `varargs.h' version of variable argument lists, you must
declare your function with a call to the macro va_alist as its
argument list, and use va_dcl as the declaration. Do not
use a semicolon after va_dcl.
Returns
These macros cannot be used in a context where a return is syntactically
possible.
Portability
va_alist and va_dcl were the most widespread method of
declaring variable argument lists prior to ANSI C.
