NAME

swab( ) - swap bytes

SYNOPSIS

#include <unistd.h>

void swab(const void *from, void *to, ssize_t nbytes);

DESCRIPTION

swab() copies nbytes bytes pointed to by from to the array pointed to by to , exchanging adjacent even

and odd bytes. It is useful for carrying binary data between byte-swapped and non-byte-swapped

machines. 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.
