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       handle pamh is no longer valid and all memory associated with it will be invalid.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.
