swabswap adjacent bytes

#include <unistd.h>

swab(const void *restrict src, void *restrict dst, ssize_t len);

The () function copies len bytes from the location referenced by src to the location referenced by dst, swapping adjacent bytes.

If len is zero or less, () does nothing. If it is odd, what happens to the last byte is unspecified. If src and dst overlap, behaviour is undefined.

bzero(3), memset(3)

The swab() function is compliant with the X/Open System Interfaces option of the IEEE Std 1003.1-2008 (“POSIX.1”) specification.

The swab() function first appeared in Version 7 AT&T UNIX.
