Say program A closes it's write half of the connection and then
Program B, which was communicating with Program A (via a pipe), then
tries to write to the fd on Program A. Program A would generate
SIGPIPE right?
If Program A generates a SIGPIPE, how can the fd on Program A be ready
for writing? Ie, if program A closes it's write end, then how can it
be ready for writing?
Huh? You said Program A has the write end of the pipe. How, then, could Program B write to it? Surely Program B has the read end.Quote:

Wait, never mind. I figured it out. And no, I wasn't using select().
