Originální popis anglicky: swab - swap adjacent bytes

Návod, kniha: Linux Programmer's Manual

STRUČNĚ

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

POPIS / INSTRUKCE

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.)

NÁVRATOVÁ HODNOTA

The swab() function returns no value.
