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

SYNOPSIS
       bcopy(src, dst, length)
       char *src, *dst;
       int length;

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

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

       ffs(i)
       int i;

DESCRIPTION
       The functions _b_c_o_p_y, _b_c_m_p, and _b_z_e_r_o operate on variable length strings
       of bytes.  They do  not  check  for  null  bytes  as  the  routines  in
       _s_t_r_i_n_g(3) do.

       _B_c_o_p_y copies _l_e_n_g_t_h bytes from string _s_r_c to the string _d_s_t.

       _B_c_m_p  compares byte string _b_1 against byte string _b_2, returning zero if
       they are identical, non-zero otherwise.  Both strings are assumed to be
       _l_e_n_g_t_h bytes long.

       _B_z_e_r_o places _l_e_n_g_t_h 0 bytes in the string _b_1.

       _F_f_s  find  the  first bit set in the argument passed it and returns the
       index of that bit.  Bits are numbered starting at 1.  A return value of
       0 indicates the value passed is zero.

BUGS
       The _b_c_o_p_y routine take parameters backwards from _s_t_r_c_p_y.
