NAME

swab - swap adjacent bytes  

SYNOPSIS

#define _XOPEN_SOURCE       /* See feature_test_macros(7) */
#include <unistd.h>void swab(const void *from, void *to, ssize_t n);
 

DESCRIPTION

The swab() function copies nbytes from the array pointed to by fromto the array pointed to by to, exchanging adjacent even and odd bytes. This function is used to exchange data between machines that have different low/high byte ordering.

This function does nothing when nis negative. When nis positive and odd, it handles n-1bytes as above, and does something unspecified with the last byte. (In other words, nshould be even.)  

RETURN VALUE

The swab() function returns no value.
