// oscsendtest.c - test o2_osc_delegate()
//
// this test is designed to run with oscrecvtest.c
//
// Usage: oscsendtest [flags] (see o2.h for flags,
// use a for all, also u for UDP, M for master)
//
// The test:
// initialize as a clock slave or master depending on M flag
// if we are master, assume we are talking to a liblo server,
// so sleep 2 seconds allowing liblo server to launch
// (you should launch it first if running manually)
// send 12 messages, 1 every 0.5s, and stop,
// message are /oscsend/i 1234
// send 10 messages with timestamps,
// messages are /oscsend/i <2000+i>
// reciever can now call o2_osc_port_free to test closing the port
// wait 1 second
// send 1 message: /oscsend/i 5678
// wait 0.1 seconds
// send 1 message with timestamp: /oscsend/i 6789
// wait 1 second
// shut everything down
