SYNOPSIS

     int
     mmeemmccmmpp(const void *b1, const void *b2, sizet len);

DESCRIPTION
     The mmeemmccmmpp() function compares byte string b1 against byte string b2.
     Both strings are assumed to be len bytes long.

RETURN VALUES
     The mmeemmccmmpp() function returns zero if the two strings are identical, oth-
     erwise returns the difference between the first two differing bytes
     (treated as unsigned char values, so that `\200' is greater than `\0',
     for example).  Zero-length strings are always identical.
