#[unsafe(no_mangle)]pub unsafe extern "C" fn pamoja_coap_client_recv(
client: *mut PamojaCoapClient,
out_message: *mut *mut PamojaMessage,
) -> PamojaStatusExpand description
Waits for the next message on an observed path.
§Arguments
client- the endpoint.out_message- receives a message handle, or null when the endpoint is closed.
§Returns
PamojaStatus::Ok on success. A null out_message with an Ok status
means the endpoint closed rather than that anything failed.
§Safety
client must be a live handle and out_message must be writable.
