eap_method::free field

free - Free EAP method data @method: Pointer to the method data registered with eap_server_method_register(). This function will be called when the EAP method is being unregistered. If the EAP method allocated resources during registration (e.g., allocated struct eap_method), they should be freed in this function. No other method functions will be called after this call. If this function is not defined (i.e., function pointer is %NULL), a default handler is used to release the method data with free(method). This is suitable for most cases.
