[Cppcms-users] Implementing chat question

[Barbu P. - G. <bar...@gm...>]

Hi.

I don't understand the bind() call when binding the arguments to 
chat::remove_context.

chat::remove_context takes only one parameter, but there are binded two, how can 
that be possible?

I'm talking about:

booster::shared_ptr<cppcms::http::context> context=release_context();
waiters_.insert(context);
context->async_on_peer_reset(
     bind(
         &chat::remove_context,
         booster::intrusive_ptr<chat>(this),
         context));

and:

void remove_context(booster::shared_ptr<cppcms::http::context> context)
{
     waiters_.erase(context);
}
