Hello,
I'm using a pipe to communicate between threads in the same process.
In fact, I've a thread waiting (using poll) for data available on some set of file descriptors.
From time to time I need to interrupt the poll call in order to add a new file descriptor. I do this with the pipe.
I add p[0] to the poll set and I write to p[1] when I want to interrupt the poll call.
The problem is that poll returns as expected, but the read on the file descriptor blocks.
Before the poll call, I set events flags to POLLIN | POLLPRI. When poll returns, events is set to POLLIN [ POLLPRI, and revents is 0. Value returned by poll is the good number of file descriptors ready.
What I'm doing wrong ?
Thanks for your help
Joe
