Wrong newsgroup. The select() call and System V IPC are not part of the C
language but part of UNIX extensions thereof.
I will tell you this: select() is a way of polling file descriptors. System V
IPC objects are not file descriptors, and their ID's are therefore not file
descriptor numbers. You are being foolhardy. In OO speak, we would say that
select() is not a method applicable to IPC objects.
