swab - swap bytes
Návod, kniha: POSIX Programmer's Manual
#include <unistd.h>
void swab(const void *restrict
src, void
*restrict dest,
ssize_t
nbytes);
The
swab() function shall copy
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 behavior is undefined. If
nbytes is negative,
swab() does nothing.
