PAM_GET_DATA(3)                          Linux-PAM Manual                         PAM_GET_DATA(3)

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.
