    1.18 +* FUNCTION
    1.19 +* <<memcmp>>---compare two memory areas
    1.20 +* INDEX
    1.21 +* memcmp
    1.22 +* ANSI_SYNOPSIS
    1.23 +* #include <string.h>
    1.24 +* int memcmp(const void *<[s1]>, const void *<[s2]>, size_t <[n]>);
    1.25 +* TRAD_SYNOPSIS
    1.26 +* #include <string.h>
    1.27 +* int memcmp(<[s1]>, <[s2]>, <[n]>)
    1.28 +* void *<[s1]>;
    1.29 +* void *<[s2]>;
    1.30 +* size_t <[n]>;
    1.31 +* This function compares not more than <[n]> characters of the
    1.32 +* object pointed to by <[s1]> with the object pointed to by <[s2]>.
    1.33 +* RETURNS
    1.34 +* The function returns an integer greater than, equal to or
    1.35 +* less than zero 	according to whether the object pointed to by
    1.36 +* <[s1]> is greater than, equal to or less than the object
    1.37 +* pointed to by <[s2]>.
    1.38 +* PORTABILITY
    1.39 +* <<memcmp>> is ANSI C.
    1.40 +* <<memcmp>> requires no supporting OS subroutines.
