UnixUtils.fdAdd

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.
