* FUNCTION
* <<memcmp>>---compare two memory areas
* INDEX
* memcmp
* ANSI_SYNOPSIS
* #include <string.h>
* int memcmp(const void *<[s1]>, const void *<[s2]>, size_t <[n]>);
* TRAD_SYNOPSIS
* #include <string.h>
* int memcmp(<[s1]>, <[s2]>, <[n]>)
* void *<[s1]>;
* void *<[s2]>;
* size_t <[n]>;
* This function compares not more than <[n]> characters of the
* object pointed to by <[s1]> with the object pointed to by <[s2]>.
* RETURNS
* The function returns an integer greater than, equal to or
* less than zero 	according to whether the object pointed to by
* <[s1]> is greater than, equal to or less than the object
* pointed to by <[s2]>.
* PORTABILITY
* <<memcmp>> is ANSI C.
* <<memcmp>> requires no supporting OS subroutines.
* QUICKREF
