PAM_GET_DATA
Section: Linux-PAM Manual (3) Updated: 04/01/2016 Index
Return to Main Contents
NAME
pam_get_data - get module internal data
SYNOPSIS
#include <security/pam_modules.h>
-
int pam_get_data(const pam_handle_t *pamh, const char *module_data_name, const void **data);
DESCRIPTION
This function together with the
pam_set_data(3)
function is useful to manage module-specific data meaningful only to the calling PAM module.
The
pam_get_data
function looks up the object associated with the (hopefully) unique string
module_data_name
in the PAM context specified by the
pamh
argument. A successful call to
pam_get_data
will result in
data
pointing to the object. Note, this data is
not
a copy and should be treated as
constant
by the module.
RETURN VALUES
PAM_SUCCESS
-
Data was successful retrieved.
PAM_SYSTEM_ERR
-
A NULL pointer was submitted as PAM handle or the function was called by an application.
PAM_NO_MODULE_DATA
-
Module data not found or there is an entry, but it has the value NULL.
