- * qemu_set_fd_handler2: Register a file descriptor with the main loop
- *
- * This function tells the main loop to wake up whenever one of the
- * following conditions is true:
- *
- * 1) if @fd_write is not %NULL, when the file descriptor is writable;
- *
- * 2) if @fd_read is not %NULL, when the file descriptor is readable.
- *
- * @fd_read_poll can be used to disable the @fd_read callback temporarily.
- * This is useful to avoid calling qemu_set_fd_handler2 every time the
- * client becomes interested in reading (or dually, stops being interested).
- * A typical example is when @fd is a listening socket and you want to bound
- * the number of active clients.  Remember to call qemu_notify_event whenever
- * the condition may change from %false to %true.
- *
- * The callbacks that are set up by qemu_set_fd_handler2 are level-triggered.
- * If @fd_read does not read from @fd, or @fd_write does not write to @fd
- * until its buffers are full, they will be called again on the next
- * iteration.
- *
- * @fd: The file descriptor to be observed.  Under Windows it must be
- * a #SOCKET.
- *
- * @fd_read_poll: A function that returns 1 if the @fd_read callback
- * should be fired.  If the function returns 0, the main loop will not
- * end its iteration even if @fd becomes readable.
- *
- * @fd_read: A level-triggered callback that is fired if @fd is readable
- * at the beginning of a main loop iteration, or if it becomes readable
- * during one.
- *
- * @fd_write: A level-triggered callback that is fired when @fd is writable
- * at the beginning of a main loop iteration, or if it becomes writable
- * during one.
- *
- * @opaque: A pointer-sized value that is passed to @fd_read_poll,
- * @fd_read and @fd_write.
