PAM_END(3) Linux-PAM Manual PAM_END(3)
pam_end - termination of PAM transaction
#include <security/pam_appl.h>
int pam_end(pam_handle_t *pamh, int pam_status);
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return the handle pamh is no longer valid and all memory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.
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.
