bstring(3)             C LIBRARY FUNCTIONS             bstring(3)



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 oth-
     erwise.  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.
