swab - Swap bytes
const void *src,
ssize_t nbytes );
The following definition of the swab() function does not
conform to current standards and is supported only for
System V compatibility: void swab(
const char *from,
int nbytes );
Standard C Library (libc)
Interfaces documented on this reference page conform to
industry standards as follows:
swab(): XPG4, XPG4-UNIX
Refer to the standards(5) reference page for more information
about industry standards and associated tags.
Points to the location of the string to copy. Points to
the location to which the resulting string is copied.
Specifies the number of bytes to be copied. The nbytes
parameter should have an even value. When the nbytes
parameter is odd, the swab() function uses nbytes-1
instead. For the System V version of the swab() function,
nbytes must also be non-negative. If nbytes is negative,
nothing is done.
The swab() function copies the number of bytes specified
by the nbytes parameter from the location pointed to by
the src parameter to the array pointed to by the dest
parameter, exchanging adjacent bytes. If copying takes
place between objects that overlap, the behavior is undefined.
