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

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.)
