VA_START(3)

NAME
15.1.1 Initialize variable argument list ----------------------------------------

SYNOPSIS
     #include <stdarg.h>
     void va_start(va_list AP, RIGHTMOST);

DESCRIPTION
Use `va_start' to initialize the variable argument list AP, so that `va_arg' can extract values from it. RIGHTMOST is the name of the last explicit argument in the parameter list (the argument immediately preceding the ellipsis `...' that flags variable arguments in an ANSI C function header). You can only use `va_start' in a function declared using this ellipsis notation (not, for example, in one of its subfunctions).

RETURNS
`va_start' does not return a result.

PORTABILITY
ANSI C requires `va_start'.
