swab(3) -- Linux man page
NAME
swab - swap adjacent bytes
SYNOPSIS
#include <unistd.h>
void swab(const void *from, void *to, ssize_t n);
DESCRIPTION
The swab() function copies n bytes from the array pointed
to by from to 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 n is negative.
When n is positive and odd, it handles n-1 bytes
as above, and does something unspecified with the last byte.
(In other words, n should be even.)
RETURN VALUE
The swab() function returns no value.
