Variable Length Argument Routines

Routine Attributes Description
va_arg reentrant Retrieves an argument from an argument list.
va_end reentrant Resets an argument pointer.
va_start reentrant Sets a pointer to the beginning of an argument list.

The variable-length argument list routines are implemented as macros and are defined in the stdarg.h include file. These routines provide a portable method of accessing arguments in functions that take a variable number of arguments. These macros conform to the ANSI C Standard for variable-length argument lists.
