how to bind a function handler?

[JellyBrick]

void handler(Message::Ptr message) {
     //do something
}

…

bot.getEvents().onCommand("start", &handler);
//or bot.getEvents().onCommand("start", handler);

Thanks,

the function void hander(Message::Ptr message), how to get access of bot object?

[JellyBrick]

Use 'global object', or use tricks.

Example)

1. Global Object

   
   TgBot::Bot bot(…)

void handler(TgBot::Message::Ptr message) { //do something }

…

bot.getEvents().onCommand("start", &handler); //or bot.getEvents().onCommand("start", handler);

2. Trick

void handler(TgBot::Message::Ptr message, TgBot::Bot& bot) { //do something } …

bot.getEvents().onCommand("start", [&bot] (TgBot::Message::Ptr message) { handler(message, bot); });
