NAME

6       bcopy, bcmp, bzero, ffs - bit and byte string operations
7

SYNOPSIS

9       bcopy(src, dst, length)
10       char *src, *dst;
11       int length;
12
13       bcmp(b1, b2, length)
14       char *b1, *b2;
15       int length;
16
17       bzero(b, length)
18       char *b;
19       int length;
20
21       ffs(i)
22       long i;

DESCRIPTION

25       The functions bcopy, bcmp, and bzero operate on variable length strings
26       of bytes.  They do  not  check  for  null  bytes  as  the  routines  in
27       string(3) do.
28
29       Bcopy copies length bytes from string src to the string dst.
30
31       Bcmp  compares byte string b1 against byte string b2, returning zero if
32       they are identical, non-zero otherwise.  Both strings are assumed to be
33       length bytes long.
34
35       Bzero places length 0 bytes in the string b1.
36
37       Ffs  find  the  first bit set in the argument passed it and returns the
38       index of that bit.  Bits are numbered starting at 1.  A return value of
39       0 indicates the value passed is zero.

BUGS

42       The bcopy routine take parameters backwards from strcpy.
