16 \fBvoid\fR \fBswab\fR(\fBvoid *\fR\fIsrc\fR, \fBvoid *\fR\fIdst\fR, \fBsize_t\fR \fInbytes\fR);
22 Architecture independent level 1 (DDI/DKI).
30 A pointer to the buffer containing the bytes to be swapped.
39 A pointer to the destination buffer where the swapped bytes will be written. If
40 \fIdst\fR is the same as \fIsrc\fR the buffer will be swapped in place.
49 Number of bytes to be swapped, rounded down to the nearest half-word.
55 The \fBswab()\fR function copies the bytes in the buffer pointed to by
56 \fIsrc\fR to the buffer pointer to by \fIdst\fR, swapping the order of adjacent
57 bytes in half-word pairs as the copy proceeds. A total of \fInbytes\fR bytes
58 are copied, rounded down to the nearest half-word.
62 The \fBswab()\fR function can be called from user, interrupt, or kernel
67 \fIWriting Device Drivers\fR
71 Since \fBswab()\fR operates byte-by-byte, it can be used on non-aligned
