прекращение транзакции PAM (termination of PAM transaction)
Имя (Name)
pam_end - termination of PAM transaction
Синопсис (Synopsis)
#include <security/pam_appl.h>
int pam_end(pam_handle_t *pamh, int pam_status);
Описание (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return the handle pamh is no longer valid and all memory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.
Возвращаемое значение (Return value)
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.
