Varying-Length Argument List Functions

This category of functions contains three macros that advance through a list of arguments whose number and type are unknown when the function is compiled. The macros are

va_arg	access an argument from a varying-length argument list
va_end	end varying-length argument list processing
va_start	begin varying length argument list processing.

These macros and the type va_list are defined in the header file <stdarg.h> . For more information on <stdarg.h> , see the function description for va_start .
