Example for playback_order_helper::modify_callback

Can somebody explain me how to use playback_order_helper::modify_callback? I want to use it but I have no idea how to do it

Create your callback function:

Code: [Select]
void callback_func (const char * newval,unsigned newidx)
{
    // do stuff in response to callback
}

Create an instance of playback_order_helper::modify_callback:

Code: [Select]
playback_order_helper::modify_callback cb(callback_func);

At least, that would be the first thing I'd try. 
Make sure you keep the modify_callback instance in scope for as long as you need the callback.

Stupid me, that was far to easy 

Thanks for helping


Btw: this is the second way this could be done:

Code: [Select]
static void callback(const config_var_string * param)
{
    string8 test;
    param->get_value(test);
    // do something
}
static config_var_callback_simple<config_var_string> meh("CORE/Playback flow control", callback, true);
