All, I have a small editor project I've worked on the past several months[1]. I want to add an `inotify` watch on the current filename after each open or save to detect modification by a foreign process. I have the details of adding the watch and polling the file descriptor with `pselect`, creating a new signal to be emitted on the inotify events, and blocking/unblocking the signal for normal saves from within the editor, but where I'm stuck is how to incorporate monitoring `pselect` from the event loop after the `inotify` watchset is created?
Where normally, you would simply call a function that would check whether input was available on the file descriptor set monitored by `pselect` in a loop, where in the GTK event loop would you incorporate the call to `pselect`? I may have the answer, but what I'm looking for in an answer is "Yes, that's a logical approach." or a "No, dummy that's going nowhere." From the glib documentation, it appears that one logical vehicle for doing this is the `g_idle_add()` function which "Adds a function to be called whenever there are no higher priority events pending to the default main loop." This seems to match exactly what I'm trying to do. I could pass a flag via the data to control the return of TRUE/FALSE to remove from the list of funcitons called when the filename changes, etc.. and within the function check the return of `pselect` for any input and emit a signal if any changes were made to the file by a foreign process between the last check and now. Is this the proper vehicle for adding/removing a bit of code to the event loop that I could use to monitor `pselect` or is there a better way of doing this? (the code is GTK+2, using the current glib functions, not the old `gtk_idle_add()`, if that makes any difference) What say the experts? footnote 1: https://github.com/drankinatty/gtkwrite -- David C.
