OK, yet another chunk of code from the Stevens' Networking book I can't
get to run. This time I realize I need the poll.h file, only I can't
find the poll.h. A few online resources suggest that some of the Unix
variants don't support Poll, just Select. Is OSX one of those that
don't support it?
Also, where can I find information about things like this so I can stop
asking for help with the easy stuff? The man pages? They have an entry
for polling, but weren't much help beyond that. I searched every drive
I could find for that file. No findey nothin.
There's no poll, just select. I wrote a substitute poll function once
(that used select internally) when I was putzing aroung with the icecast
server source months ago, but I can't find it at the moment. It wasn't
terribly difficult, but I can't type it out from memory...
Don't trust the man pages -- at times, the man pages seem to be for a
different operating system... Use the source (the headers) for the
definitive answers. The 'locate' command can be really, really handy for
this sort of thing (ie., 'locate poll.h', and it won't find it). grep is
nice for this too, especially with the recursive flag (ie., 'grep -r
poll /usr/include/*' Of course, that won't find it either, since it's
not there).
