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 Upon return the handle pamh is no longer valid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 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.
