.SH NAME
csx_ReleaseConfiguration \- release PC Card and socket configuration
.SH SYNOPSIS
.LP
.nf
#include <sys/pccard.h>
\fBint32_t\fR \fBcsx_ReleaseConfiguration\fR(\fBclient_handle_t\fR \fIch\fR, \fBrelease_config_t *\fR\fIrc\fR);
.fi
.SH INTERFACE LEVEL
.sp
.LP
Solaris \fBDDI\fR Specific (Solaris \fBDDI\fR)
.SH PARAMETERS
.sp
.ne 2
.na
\fB\fIch\fR \fR
.ad
.RS 7n
Client handle returned from \fBcsx_RegisterClient\fR(9F).
.RE
.sp
.ne 2
.na
\fB\fIrc\fR \fR
.ad
.RS 7n
Pointer to a \fBrelease_config_t\fR structure.
.RE
.SH DESCRIPTION
.sp
.LP
This function returns a \fBPC\fR Card and socket to a simple memory only
interface and sets the card to configuration zero by writing a \fB0\fR to the
\fBPC\fR card's \fBCOR\fR (Configuration Option Register).
.sp
.LP
Card Services may remove power from the socket if no clients have indicated
their usage of the socket by an active \fBcsx_RequestConfiguration\fR(9F) or
\fBcsx_RequestWindow\fR(9F).
.sp
.LP
Card Services is prohibited from resetting the \fBPC\fR Card and is not
required to cycle power through zero (\fB0\fR) volts.
.sp
.LP
After calling \fBcsx_ReleaseConfiguration()\fR any resources requested via the
request functions \fBcsx_RequestIO\fR(9F), \fBcsx_RequestIRQ\fR(9F), or
\fBcsx_RequestWindow\fR(9F) that are no longer needed should be returned to
Card Services via the corresponding \fBcsx_ReleaseIO\fR(9F),
\fBcsx_ReleaseIRQ\fR(9F), or \fBcsx_ReleaseWindow\fR(9F) functions.
\fBcsx_ReleaseConfiguration()\fR must be called to release the current card and
socket configuration before releasing any resources requested by the driver via
the request functions named above.
.SH STRUCTURE MEMBERS
.sp
.LP
The structure members of \fBrelease_config_t\fR are:
.sp
.in +2
.nf
uint32_t Socket; /* socket number */
.fi
.in -2
.sp
.LP
The \fBSocket\fR field is not used in Solaris, but for portability with other
Card Services implementations, it should be set to the logical socket number.
.SH RETURN VALUES
.sp
.ne 2
.na
\fB\fBCS_SUCCESS\fR \fR
.ad
.RS 28n
Successful operation.
.RE
.sp
.ne 2
