Waits until an event is received from the BrlAPI server
Parameters
timeout_ms specifies an optional timeout which can be zero for polling, or -1 for infinite wait
Returns
0 on timeout, -1 on error, or on interruption by a signal or a parameter change notification, in which case brlapi_errno will be BRLAPI_ERROR_LIBCERR and errno will be EINTR.
