Is there any way to execute a callback (on Linux) when a file descriptor is closed

QUESTION

Is there any way to execute a callback (on Linux) when a file descriptor is closed

Asked 2019-Sep-15 at 18:24

I'm working on a kevent/kqueue emulation library for Linux. I'm a new maintainer on this project, and unfortunately, the previous maintainer is not involved much anymore (so I can't pick their brains about this).

Under FreeBSD and macOS when you close() the file descriptor provided by kqeueue() you free any resources and events associated with it.

It seems like the existing code doesn't provide a similar interface. Before I add a function to the API (or revive an old one) to explicitly free kqueue resources, I was wondering if there was any way to associate triggers with a file descriptor in linux, so that when it's closed we can cleanup anything associated with the FD.

The file descriptor itself could be any type, i.e. one provided by eventfd, or epoll or anything else that creates file descriptors.

When the last write file descriptor from a pipe() call is closed epoll()/poll() waiters will see an [E]POLLHUP event on any read file descriptors still open. Presumably the same is true of any fd that represents a connection rather than state.
