Undocumented Sigvec Calls?

I am developing a checkpoint utility on an encore multimax machine and came
across a problem which manifested itself during a profile run.

Sigvec is used to send information about a sigentry procedure to the kernel.
It uses signal 1024 (0x400) to send this information although it does return
-1.

My questions are :-
	Is this documented somewhere?
	If so, where?
	Are there any more of these lying about for any more system calls?

Thanks
	Kev
