Prev	Chapter 3. What is expected of a module	Next

To be correctly initialized, PAM_SM_SESSION must be #define'd prior to including <security/pam_modules.h>. This will ensure that the prototypes for static modules are properly declared.

3.4.1. Service function to start session management

#define PAM_SM_SESSION

#include <security/pam_modules.h>

`PAM_EXTERN int pam_sm_open_session(`	`pamh`,
	`flags`,
	`argc`,
	`argv)`;

pam_handle_t *pamh;
int flags;
int argc;
const char **argv;

3.4.1.1. 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.

3.4.1.2. RETURN VALUES

PAM_SESSION_ERR: Cannot make/remove an entry for the specified session.
PAM_SUCCESS: The session was successfully started.

3.4.2. Service function to terminate session management

#define PAM_SM_SESSION

#include <security/pam_modules.h>

`PAM_EXTERN int pam_sm_close_session(`	`pamh`,
	`flags`,
	`argc`,
	`argv)`;

pam_handle_t *pamh;
int flags;
int argc;
const char **argv;

3.4.2.1. DESCRIPTION

The pam_sm_close_session function is the service module's implementation of the pam_close_session(3) interface.

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

PAM_SILENT: Do not emit any messages.

3.4.2.2. RETURN VALUES

PAM_SESSION_ERR: Cannot make/remove an entry for the specified session.
PAM_SUCCESS: The session was successfully terminated.
