Name

bcmp — compare byte sequences

Synopsis

        #include <strings.h>
int bcmp( const void *s1,
  const void *s2,
  size_t n);

The bcmp() function compares the two byte sequences s1 and s2 of length n each. If they are equal, and in particular if n is zero, bcmp() returns 0. Otherwise, it returns a nonzero result.

RETURN VALUE

The bcmp() function returns 0 if the byte sequences are equal, otherwise a nonzero result is returned.
