NAME
pam_end - termination of PAM transaction
SYNOPSIS
#include <security/pam_appl.h>
-
int pam_end(pam_handle_t *pamh, int pam_status);
DESCRIPTION
The
pam_end
function terminates the PAM transaction and is the last function an application should call in the PAM context. Upon return the handle
pamh
is no longer valid and all memory associated with it will be invalid.
The
pam_status
argument should be set to the value returned to the application by the last PAM library call.
The value taken by
pam_status
is used as an argument to the module specific callback function,
cleanup()
(See
pam_set_data(3)
and
pam_get_data(3)). In this way the module can be given notification of the pass/fail nature of the tear-down process, and perform any last minute tasks that are appropriate to the module before it is unlinked. This argument can be logically OR'd with
PAM_DATA_SILENT
to indicate to indicate that the module should not treat the call too seriously. It is generally used to indicate that the current closing of the library is in a
fork(2)ed process, and that the parent will take care of cleaning up things that exist outside of the current process space (files etc.).
This function
free's all memory for items associated with the
pam_set_item(3)
and
pam_get_item(3)
functions. Pointers associated with such objects are not valid anymore after
pam_end
was called.
RETURN VALUES
PAM_SUCCESS
-
Transaction was successful terminated.
PAM_SYSTEM_ERR
-
System error, for example a NULL pointer was submitted as PAM handle or the function was called by a module.
