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
swab() 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
swab() can be called from user or interrupt context.
SEE ALSO
Writing Device Drivers
NOTES
Since swab() operates byte-by-byte, it can be used on non-aligned buffers. SunOS 5.10 1 Feb 1991 swab(9F)
