rtdm_event_pulse() is part of the inter-driver API, which explains why
there is no userland access to it. Assuming you need to wake up a RTDM
task waiting on a particular event via rtdm_event_wait(), then you have
to implement an rt/nrt ioctl handler in your RTDM driver which will send
the event. Userland can issue this ioctl request from userland.
