NAME
       swab - swap bytes

SYNOPSIS
       swab(from, to, nbytes)
       char *from, *to;

DESCRIPTION
       _S_w_a_b  copies _n_b_y_t_e_s bytes pointed to by _f_r_o_m to the position pointed to
       by _t_o_, exchanging adjacent even and odd bytes.  It is useful for carry‐
       ing  binary  data between PDP11’s and other machines.  _N_b_y_t_e_s should be
       even.
