NAME
swab - swap bytes
SYNOPSIS
void swab (from, to, nbytes)
char *from, *to;
int nbytes;
DESCRIPTION
The swab function 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.
