VARARGS(3-ucb)	  Pyramid OSx Operating	System	   VARARGS(3-ucb)



NAME
     varargs - variable	argument list

SYNOPSIS
     #include <varargs.h>

     function(va_alist)
     va_dcl
     va_list pvar;
     va_start(pvar);
     f = va_arg(pvar, type);
     va_end(pvar);

DESCRIPTION
     This set of macros	provides a means of writing portable pro-
     cedures that accept variable argument lists.  Routines hav-
     ing variable argument lists (such as printf(3)) that do not
     use varargs are inherently	nonportable, since different
     machines use different argument passing conventions.
