How to test user written program on Jackd

Hello Guys,

I am playing around with Jackd (Jack Audio Connection Kit). So far, successfully I connect with RtAudio with Jack Daemon. Last time I could not combine DSPatch (C++ programming Library) with jack in present of RtAudio. Now it is fixed, Currently I am looking how to check a user-define program to check on Jackd e.g latency and delay, if anyone has good tips for me how to work on, feel free to let me know.

Thanks in Advanced.
