bstring(3)         UNIX System V(BSD Compatibility Package)          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 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.

NOTES
      The bcmp and bcopy routines take parameters backwards from strcmp and
      strcpy.
