NAME

       pam_sm_open_session - PAM service function to start session management

SYNOPSIS

       #define PAM_SM_SESSION

       #include <security/pam_modules.h>

       PAM_EXTERN int pam_sm_open_session(pam_handle_t *pamh, int flags, int argc, const char **argv);

DESCRIPTION

       The pam_sm_open_session function is the service module's implementation of the pam_open_session(3) interface.

       This function is called to commence a session. The only valid value for flags is zero or:

       PAM_SILENT
	   Do not emit any messages.

RETURN VALUES

       PAM_SESSION_ERR
	   Cannot make/remove an entry for the specified session.

       PAM_SUCCESS

NAME

       pam_sm_open_session, pam_sm_close_session - service provider implementation for pam_open_session and pam_close_session

SYNOPSIS

       cc [ flag ... ]	file ... -lpam [ library ... ]
       #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(3PAM)  and  pam_close_session(3PAM),  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.

       The  pam_sm_open_session()  function is called to initiate session management. Thepam_sm_close_session() function 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.

RETURN VALUES

       Upon successful completion,  PAM_SUCCESS should be returned. The following values may also be returned upon error:

       PAM_SESSION_ERR	  Cannot make or remove an entry for the specified session.

       PAM_IGNORE	  Ignore underlying session module regardless of whether the control  flag is required, optional or sufficient.
