11 int pam_end(pam_handle_t *pamh, int pam_status);
12
14 The pam_end function terminates the PAM transaction and is the last
15 function an application should call in the PAM context. Upon return the
16 handle pamh is no longer valid and all memory associated with it will
17 be invalid.
18
19 The pam_status argument should be set to the value returned to the
20 application by the last PAM library call.
21
22 The value taken by pam_status is used as an argument to the module
23 specific callback function, cleanup() (See pam_set_data(3) and
24 pam_get_data(3)). In this way the module can be given notification of
25 the pass/fail nature of the tear-down process, and perform any last
26 minute tasks that are appropriate to the module before it is unlinked.
27 This argument can be logically OR´d with PAM_DATA_SILENT to indicate to
28 indicate that the module should not treat the call too seriously. It is
29 generally used to indicate that the current closing of the library is
30 in a fork(2)ed process, and that the parent will take care of cleaning
31 up things that exist outside of the current process space (files etc.).
32
33 This function free´s all memory for items associated with the
34 pam_set_item(3) and pam_get_item(3) functions. Pointers associated with
35 such objects are not valid anymore after pam_end was called.
36
38 PAM_SUCCESS
39 Transaction was successful terminated.
40
41 PAM_SYSTEM_ERR
42 System error, for example a NULL pointer was submitted as PAM
43 handle or the function was called by a module.
