addPoll

Adds a file descriptor to the set of file descriptors polled for this source. This is usually combined with ctor@GLib.Source.new to add an event source. The event source's check function will typically test the @revents field in the #GPollFD struct and return true if events need to be processed.

This API is only intended to be used by implementations of struct@GLib.Source. Do not call this API on a struct@GLib.Source that you did not create.

Using this API forces the linear scanning of event sources on each main loop iteration. Newly-written event sources should try to use g_source_add_unix_fd instead of this API.
