Nope, the remote side didn't got an event, (dat_evd_wait timed out).
The way to find out the immed data is to check the out going
parameter &event of dat_evd_wait function.

&event.event_extension_data[0]->val.immed.data has not got a value yet.

Yes, I do checked this test program. The way to use 
dat_ib_post_rdma_write_immed
is as same as dtestx.
