pam_get_data: get module internal data
pam_get_data - get module internal data
int pam_get_data(const pam_handle_t
*pamh, const char *module_data_name, const void **data);
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.
- Data was successful retrieved.
- A NULL pointer was submitted as PAM handle or the function was called by an application.
- Module data not found or there is an entry, but it has the value NULL.
