Re: max filedescriptor on linux

Unfortunally that's wrong, my practice says select() IS limited to 1024FD
(or whatever is in some #defines at the time the kernel is compiled) i
learned it by the hardest way (a IRC server i'd maintain)

I'v recently started a "thread" in "comp.os.linux.*" & "linux.dev.kernel.*"
the people that answer-me have confirmed that limitation of select().

Take a look at the linux kernel. 8((

Best Regards.

PS: For a turnaround to this limitation, someone sugested-me the procedure
described in http://www.volano.com/linux.html "Linux 2.2 kernel file
descriptors and tasks" (implies kernel recompilation)
