Function panda_sys::object_child_foreach

pub unsafe extern "C" fn object_child_foreach(
    obj: *mut Object,
    fn_: Option<unsafe extern "C" fn(child: *mut Object, opaque: *mut c_void) -> c_int>,
    opaque: *mut c_void
) -> c_int

object_child_foreach: @obj: the object whose children will be navigated @fn: the iterator function to be called @opaque: an opaque value that will be passed to the iterator

Call @fn passing each child of @obj and @opaque to it, until @fn returns non-zero.

It is forbidden to add or remove children from @obj from the @fn callback.

Returns: The last value returned by @fn, or 0 if there is no child.
