Socket Problem on SunOS 4.03

[P Sember SNR]

	I have a problem with UNIX Domain sockets under 4.03 SunOS.
	Using Internet Domain sockets I can arrange a SIGIO to be 
	generated and caught by a handler, when the socket contains
	data to be read using: 

		sigvec(SIGIO,&newvec,&oldvec);
		fcntl(skt, F_SETOWN, getpid())
		fcntl(skt, F_SETFL, FASYNC) 

	However I can't have a SIGIO generated when there is data on
	an UNIX domain socket.


	Please send replies to my email address
