PAM_END(3)                    Linux-PAM Manual                    PAM_END(3)

NAME         top

       pam_end - termination of PAM transaction

SYNOPSIS         top

       #include <security/pam_appl.h>

       int pam_end(pam_handle_t *pamh, int pam_status);

DESCRIPTION         top

       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       the handle pamh is no longer valid and all memory associated with it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         top

       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.
