NAME
swab - swap adjacent bytes SYNOPSIS
#define _XOPEN_SOURCE #include <unistd.h> void swab(const void *from, void *to, ssize_t n); DESCRIPTION
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.) RETURN VALUE
The swab() function returns no value. CONFORMING TO
SVr4, 4.3BSD, POSIX.1-2001. SEE ALSO

NAME
swab - swap bytes SYNOPSIS
#include <stdlib.h> void swab(const char *src, char *dest, ssize_t nbytes); XPG4, SUS, SUSv2, SUSv3 #include <unistd.h> void swab(const void *restrict src, void *restrict dest, ssize_t nbytes); DESCRIPTION
The swab() function copies 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 unspec- ified. If copying takes place between objects that overlap, the behavior is undefined. If nbytes is negative, swab() does nothing. ERRORS
No errors are defined. ATTRIBUTES
