Subject: SIGIO interrupts poll
Date: Tue,  3 Feb 2004 11:59:40 -0500 (EST)	[thread overview]
Message-ID: <20040203165940.CE70839A1@mprdmxin.myway.com> (raw)


I'm working on a large software project and two of the developers have coded each other into a corner.

Specifically, one thread catches SIGIO to read from a hardware device over the serial port. A second thread uses poll() to read from some sockets to other computers.

Independently they work, but when put together the thread that catches SIGIO is preventing the socket-reading thread from getting any of its data.

Is there a way to have the SIGIO handler re-throw the signal so the thread using poll() can catch it?

Andrea
