/**
* g_unix_fd_add:
* @fd: a file descriptor
* @condition: IO conditions to watch for on @fd
* @function: a #GUnixFDSourceFunc
* @user_data: data to pass to @function
*
* Sets a function to be called when the IO condition, as specified by
* @condition becomes true for @fd.
*
* @function will be called when the specified IO condition becomes
* %TRUE. The function is expected to clear whatever event caused the
* IO condition to become true and return %TRUE in order to be notified
* when it happens again. If @function returns %FALSE then the watch
* will be cancelled.
*
* The return value of this function can be passed to g_source_remove()
* to cancel the watch at any time that it exists.
*
* The source will never close the fd -- you must do it yourself.
*
* Returns: the ID (greater than 0) of the event source
*
* Since: 2.36
