I/O Completion Ports (1 of 2)

[Robert Shearman]

I will try to fix this sometime in the next week, depending on whether I
can get CVS access to take advantage of the work Eric Pouech has done.

You cannot send different message sizes into the wait_fd pipe, this
won't work since pipes don't preserve message boundaries. I'd suggest
simply using the normal wait mechanism and then doing a separate call
to retrieve the rest of the info.
