Example: lrs_get_last_received_buffer_size

In the following example, we check if data was received on a socket using lrs_get_last_received_buffer_size. If not we send an error message.

lrs_receive("socket2", "buf20", LrsLastArg); 

if (lrs_get_last_received_buffer_size("socket2") < 1) {

    lr_error_message("No data received on socket2");

    return -1

}
