Anonymous functions

[Pelle Beckman]

Does C++ in some way support anonymous functions?

Say I have a callback function that I register
with SetCallback() (this perticular example
is from my attempts at messages, signals, events, etc
in a GUI for a game)

Would something in this way be possible:
(I know Java can do it...)

SetCallback (new function() = {
my_var++;
std::cout << "Hello!" << std::endl;
});


Thanks!

SetCallback (new function() = {
my_var++;
std::cout << "Hello!" << std::endl;
});

Maybe Boost.Lambda libray could help you:
http://www.boost.org/doc/html/lambda.html

It requires fairly compatible compiler.
