NAME

swab - swap
bytes in 16-bit halfwords
 

SYNOPSIS

#include <sys/sunddi.h>



void swab(void *src, void *dst, size_t nbytes);

INTERFACE LEVEL

Architecture independent level 1 (DDI/DKI).  

PARAMETERS

src

A pointer to the buffer containing the bytes to be swapped.

dst

A pointer to the destination buffer where the swapped bytes will be written. If dst is the same as src the buffer will be swapped in place.

nbytes

Number of bytes to be swapped, rounded down to the nearest half-word.

DESCRIPTION

The swab() function copies the bytes in the buffer pointed to by src to the buffer pointer to by dst, swapping the order of adjacent bytes in half-word pairs as the copy proceeds. A total of nbytes bytes are copied, rounded down to the nearest half-word.  

CONTEXT

The swab() function can be called from user, interrupt, or kernel context.  

SEE ALSO

Writing Device Drivers  

NOTES

Since swab() operates byte-by-byte, it can be used on non-aligned buffers.
