NAME

swab − swap bytes

SYNOPSIS

#include <stdlib.h>

void swab(const char ∗from, char ∗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.
