- The patch for exceptional conditions is interesting, but can someone
- explain what an exception condition is? Would be something like, someone
- closing a pipe your reading? Or a media change on the drive for which
- you are doing IO? Or maybe a loss of carrier?
-
- Or is an exceptional condition something else?
-
- How do read the condition? Fread?
-
- Is it possible to use an exception condition with Fselect, to "wait for
- carrier" or to detect the loss of such (so, could you wait for a change
- in the carrier status?)
-
- If so, then this would be very useful indeed.
