.SH INTERFACE LEVEL
.sp
.LP
Solaris DDI specific (Solaris DDI). The \fBddi_putb()\fR, \fBddi_putl()\fR, \fBddi_putll()\fR, and \fBddi_putw()\fR functions are obsolete. The \fBddi_put8()\fR function replaces \fBddi_putb()\fR. The \fBddi_put32()\fR function replaces \fBddi_putl()\fR. The \fBddi_put64()\fR function replaces \fBddi_putll()\fR. The \fBddi_put16()\fR function replaces \fBddi_putw()\fR.

.SH DESCRIPTION
.sp
.LP
These routines generate a write of various sizes to the mapped memory or device register. The \fBddi_put8()\fR, \fBddi_put16()\fR, \fBddi_put32()\fR, and \fBddi_put64()\fR functions write 8 bits, 16 bits, 32 bits and 64 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.
.sp
.LP
For certain bus types, you can call these \fBDDI\fR functions from a high-interrupt context. These types include \fBISA\fR and SBus buses. See \fBsysbus\fR(4) and \fBisa\fR(4) for details. For the PCI bus, you can, under certain conditions, call these \fBDDI\fR functions from a high-interrupt context. See \fBpci\fR(4). 
.SH CONTEXT
.sp
.LP
These functions can be called from user, kernel, or interrupt context.
