pam_get_data

get module internal data

         #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.
