.fi
.SH DESCRIPTION
In response to a call to \fBpam_open_session\fR(3PAM) and
\fBpam_close_session\fR(3PAM), the \fBPAM\fR framework calls
\fBpam_sm_open_session()\fR and \fBpam_sm_close_session()\fR, respectively from
the modules listed in the \fBpam.conf\fR(5) file. The session management
provider supplies the back-end functionality for this interface function.
.sp
.LP
The \fBpam_sm_open_session()\fR function is called to initiate session
management. The \fBpam_sm_close_session()\fR function is invoked when a session
has terminated. The argument \fIpamh\fR is an authentication handle. The
following flag may be set in the \fIflags\fR field:
.sp
.ne 2
.na
\fB\fBPAM_SILENT\fR\fR
.ad
.RS 14n
Session service should not generate any messages.
.RE
.sp
.LP
The \fIargc\fR argument represents the number of module options passed in from
the configuration file \fBpam.conf\fR(5). \fIargv\fR specifies the module
options, which are interpreted and processed by the session management service.
If an unknown option is passed in, an error should be logged through
\fBsyslog\fR(3C) and the option ignored.
.SH RETURN VALUES
Upon successful completion, \fBPAM_SUCCESS\fR should be returned. The
following values may also be returned upon error:
.sp
.ne 2
.na
\fB\fBPAM_SESSION_ERR\fR\fR
.ad
.RS 19n
Cannot make or remove an entry for the specified session.
.RE
.sp
.ne 2
.na
\fB\fBPAM_IGNORE\fR\fR
.ad
.RS 19n
Ignore underlying session module regardless of whether the control flag is
\fIrequired\fR, \fIoptional\fR or \fIsufficient\fR.

multithreaded application uses its own \fBPAM\fR handle.
