NAME

swab — swap bytes

SYNOPSIS

#include <unistd.h>

void swab(const void *src, void *dest, ssize_t nbytes);

DESCRIPTION

The swab() function copies nbytes bytes, which are pointed to by src , to the object pointed to by dest , exchanging adjacent bytes. The nbytes argument should be even. If nbytes is odd swab() copies and exchanges nbytes -1 bytes and the disposition of the last byte is unspecified. If copying takes place between objects that overlap, the behaviour is undefined. If nbytes is negative, swab() does nothing.
