NAME
swab - swap bytes
SYNOPSIS
void swab (from, to, nbytes)
char *from, *to;
int nbytes;
DESCRIPTION
swab copies nbytes bytes pointed to by from to the array
pointed to by to, exchanging adjacent even and odd bytes.
Nbytes should be even and non-negative. If nbytes is odd
and positive swab uses nbytes-1 instead. If nbytes is
negative, swab does nothing.
