How to pass a method as callback to another class?

Question

I have a question regarding callbacks using tr1::function. I\'ve defined the following:

  class SomeClass {
    public:
      typedef std::tr1::function

        

Answer 1

the function void (*)(unsigned char*, int) is a free function, which is a different type from void (SomeOtherClass::*)(unsigned char*, int), thus the error. You need an object to call the latter, while the former is a free function.

Look at the possible solutions listed in the Boost documentation

Another possibility is that your SomeOtherClass::myCallback is private, so you do not have access to it.
