Hi All, This is really not a beginner question but I'm not sure what list to post it on.
I've created a daemon library for easily building daemons and at some point code was added to handle closing all fd's so the daemonized process would not have fd's hanging around it shouldn't have or didn't expect to have. The code to close the fd was using POSIX::close(), and this was a bad idea because, though it closes the fd, it leaves any perl filehandles associated with the fd hanging around. This makes for really twisty and perplexing bugs. So I don't want to do that, but I can't figure out for the life of me how to get a hold of all filehandles associated with an fd, or to close all filehandles associated with an fd. Is there a way to do this? I tried walking through the symbol tables, but that won't get lexically scoped and localized filehandles. How does one do this? BTW, at this moment I'm looking through perlio.c to try to see how the filehandles and fd's are managed internally. If I had to I could write a c routine to do this and expose it through XS. Any clues in this area though, would be nice (like is there something already in perlio.c to do this (-:). And of course pointing me to a more appropriate list is fine too.
