Problems with SIGPOLL using libsocket.a (BSD)

[Christian Kasperbauer]

Hi out there,

perhaps that's the wrong newsgroup for my request, I don't know, but I've the
following problem, so if anyone can help me, please answer:

I'm writing a client/server application between a Sun Sparc and a Intel i386
workstation using Berkley stream sockets. The server is running on the i386 and
is implemented as a UNIX daemon, i.e. he is sleeping until a SIGPOLL signal
arrives. On the i386 runs INTERACTIVE 386/ix and I'm using the libsocket.a
library, which emulates Berkley sockets on System V streams.

I did the following steps to initialize the sockets:
		sock[i] = open (AF_INET, SOCK_STREAM, IP)
		...
		bind (sock[i], ...
		...
		FD_SET (sock[i], read_template);
#ifdef SYSV
		ioctl (sock[i], I_SETSIG, S_INPUT);
#else
		fcntl (sock[i], F_SETOWN, getpid ());
		fcntl (sock[i], F_SETFL, FASYNC);
#endif
		...

The daemon's signal handler is of the following form:
		void handler ()
		...
		hlp = read_template;
		while (select (FD_SETSIZE, &hlp, NULL, NULL &timeout) > 0)
			 ...
			 /* poll sockets
				*/
       ...

The problem is, no SIGPOLL signal arrives, but under BSD this code runs fine
(for example between a VAX and a Sun or an Alliant FX2800). So my question is,
what did I forget to initialize? AT&T handbooks deal only with System V
streams, i.e. the poll() system call, which I don't want to use. Is there a 
difference between SIGIO (BSD) and SIGPOLL (System V)? Does anyone know a
correct solution for this problem or a tricky work around?

Hope to receive a positive answer,
Christian

P.S.: Please answer by e-mail, I don't read frequently this newsgroup.
