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

NAME         top

       pam_get_data - get module internal data

SYNOPSIS         top

       #include <security/pam_modules.h>

       int pam_get_data(const pam_handle_t *pamh,
                        const char *module_data_name, const void **data);

DESCRIPTION         top

       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         top

       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.
