int(* fuse_operations::poll)(const char *, struct fuse_file_info *, struct fuse_pollhandle *ph, unsigned *reventsp)

Poll for IO readiness events

Note: If ph is non-NULL, the client should notify when IO readiness events occur by calling fuse_notify_poll() with the specified ph.

Regardless of the number of times poll with a non-NULL ph is received, single notification is enough to clear all. Notifying more times incurs overhead but doesn't harm correctness.

The callee is responsible for destroying ph with fuse_pollhandle_destroy() when no longer in use.

Introduced in version 2.8
