Имя (Name)
swab — swap bytes
Синопсис (Synopsis)
#include <unistd.h>
void swab(const void *restrict src, void *restrict dest,
ssize_t nbytes);
Описание (Description)
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.
