#include <security/pam_appl.h>
#include <security/pam_modules.h>
int pam_sm_open_session(pam_handle_t *pamh,
int flags,
int argc,
const char **argv);
int pam_sm_close_session(pam_handle_t *pamh,
int flags,
int argc,
const char **argv);
DESCRIPTION
In response to a call to
pam_open_session()
and
pam_close_session(),
the PAM framework calls
pam_sm_open_session()
and
pam_sm_close_session(),
respectively from the modules listed in the
pam.conf(4)
file. The session management provider supplies the back-end functionality for
this interface function.
pam_sm_open_session()
is called to initiate session management.
pam_sm_close_session()
is invoked when a session has terminated.
The argument
pamh
is an authentication handle.
The following flag may be set in the
flags
field:
- PAM_SILENT
Session service should not generate any messages.
The
argc
argument
represents the number of module options passed in from the configuration file
pam.conf(4).
argv
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
syslog(3C)
and the option ignored.
APPLICATION USAGE
Refer to
pam(3)
for information on thread-safety of PAM interfaces.
RETURN VALUES
Upon successful completion,
PAM_SUCCESS
should be returned.
The following values may also be returned upon error:
- PAM_SESSION_ERR
Can not make/remove an entry for the specified session.
- PAM_IGNORE
Ignore underlying session module regardless of whether the control
flag is
required,
optional
or
sufficient
