bit and byte string operations

NAME
bstring: bcopy, bcmp, bzero, ffs - bit and byte string operations
SYNOPSIS
cc [ flag... ] file ... -lucb bcopy(b1, b2, length) char *b1, *b2; int length; int bcmp(b1, b2, length) char *b1, *b2; int length; bzero(b, length) char *b; int length;
DESCRIPTION
The functions bcopy, bcmp, and bzero operate on variable length strings of bytes. They do not check for null bytes as the routines in string(3) do. bcopy copies length bytes from string b1 to the string b2. Overlapping strings are handled correctly. bcmp compares byte string b1 against byte string b2, returning zero if they are identical, 1 otherwise. Both strings are assumed to be length bytes long. bcmp of length zero bytes always returns zero. bzero places length 0 bytes in the string b.
CAVEAT
The bcmp and bcopy routines take parameters backwards from strcmp and strcpy.
