* 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

* memcmp ansi pure
