Are you calling rtdm_event_wait() from a non-RT context? I noticed in my
application* that rtdm_event_wait() always returns 0 in non-RT and I
needed to ensure rtdm_event_wait() is only called from RT context.

I'm not sure if 0 is the intended return value or not, but the
documentation does specify that NRT isn't a valid calling context.
