Pointer to a data access handle.
.RE
.SH DESCRIPTION
.LP
\fBpci_config_setup()\fR sets up the necessary resources for enabling
subsequent data accesses to the \fBPCI \fRLocal Bus Configuration space.
\fBpci_config_teardown()\fR reclaims and removes those resources represented
by the data access handle returned from \fBpci_config_setup()\fR.
.SH RETURN VALUES
.LP
\fBpci_config_setup()\fR returns:
.sp
.ne 2
.na
\fB\fBDDI_SUCCESS\fR \fR

.RE
.SH CONTEXT
.LP
\fBpci_config_setup()\fR must be called from user or kernel context.
\fBpci_config_teardown()\fR can be called from any context.
.SH NOTES
.LP
These functions are specific to \fBPCI \fRbus device drivers. For drivers using
these functions, a single source to support devices with multiple bus versions
may not be easy to maintain.
