.LP
Solaris DDI specific (Solaris DDI). The \fBddi_io_put8()\fR, \fBddi_io_put16()\fR, \fBddi_io_put32()\fR, \fBddi_io_putb()\fR, \fBddi_io_putl()\fR, and \fBddi_io_putw()\fR functions are obsolete. The \fBddi_put8\fR(9F) function replaces \fBddi_io_put8()\fR. The \fBddi_put16\fR(9F) function replaces \fBddi_io_put16()\fR. The \fBddi_put32\fR(9F) function replaces \fBddi_io_put32()\fR. The \fBddi_put8\fR(9F) function replaces \fBddi_io_putb()\fR. The \fBddi_put32\fR(9F) function replaces \fBddi_io_putl()\fR. The \fBddi_put16\fR(9F) function replaces \fBddi_io_putw()\fR.

.SH DESCRIPTION
.sp
.LP
These routines generate a write of various sizes to the device address, \fIdev_addr\fR, in I/O space. The \fBddi_io_put8()\fR, \fBddi_io_put16()\fR, and \fBddi_io_put32()\fR functions write 8 bits, 16 bits, and 32 bits of data, respectively, to the device address, \fIdev_addr\fR.
.sp
.LP
Each individual datum will automatically be translated to maintain a consistent view between the host and the device based on the encoded information in the data access handle.  The translation may involve byte-swapping if the host and the device have incompatible endian characteristics.
.SH CONTEXT
.sp
.LP
These functions can be called from user, kernel, or interrupt context.
