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handle pamh is no
longer valid and all memory associated with it will be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.
Transaction was successful terminated.
System error, for example a NULL pointer was submitted as PAM handle or the function was called by a module.
