bstring(3)                                             bstring(3)



     NAME
          bcopy, bcmp, bzero - bit and byte string operations

     SYNOPSIS
          #include <sys/param.h>

          int bcopy(b1, b2, length)
          char *b1, *b2;
          int length;

          int bcmp(b1, b2, length)
          char *b1, *b2;
          int length;

          int bzero(b, length)
          char *b;
          int length;

     DESCRIPTION
          The macro bcopy, and the functions bcmp and bzero operate on
          variable length strings of bytes.  They do not check for
          null bytes as the routines in string(3C) do.

          bcopy copies length bytes from string b1 to the string b2.

          bcmp compares byte string b1 against byte string b2, return-
          ing zero if they are identical, nonzero otherwise.  Both
          strings are assumed to be length bytes long.

          bzero places length 0 bytes in the string b1.

     FILES
          /usr/include/sys/param.h

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