Pointer to a \fBscsi_pkt\fR(9S) structure.

.SH INTERFACE LEVEL
.sp
.LP
Solaris DDI specific (Solaris DDI).
.SH DESCRIPTION
.sp
.LP
After filling in \fBscsi_pkt\fR(9S) fields with packet completion information, an HBA driver should call the \fBscsi_hba_pkt_comp()\fR function. This function is the recommended way for an HBA driver to signal completion of a \fBscsi_pkt\fR structure.  Use is mandatory for HBA drivers that use \fBtran_setup_pkt\fR(9E).
.sp
.LP
Calling the \fBscsi_hba_pkt_comp()\fR function allows SCSA to observe, and possibly react to, the completion of a \fBscsi_pkt\fR request.
.sp
.LP
A call to the \fBscsi_hba_pkt_comp()\fR function will always result in a call to the \fIpkt_comp\fR() callback function defined in \fBscsi_pkt\fR(9S). This \fIpkt_comp\fR() callback may, however, occur after return from \fBscsi_hba_pkt_comp()\fR, and may occur from a different thread executing on a different CPU.
.SH CONTEXT
.sp
.LP
The \fBscsi_hba_pkt_comp()\fR function can be called from user, interrupt, or kernel context.

.SH NOTES

.LP
HBA driver calls \fBscsi_hba_pkt_comp()\fR instead of calling \fBscsi_pkt\fR(9S) \fIpkt_comp\fR directly.
