bindconstmemfunc 

For const member functions, we only need a const class pointer. Since we know that the member function is const, it's safe to remove the const qualifier from the 'this' pointer with a const_cast. VC6 has problems if we just overload 'bindmemfunc', so we give it a different name. 

 

bindmemfunc 

At present, GCC doesn't recognize constness of MFPs in templates 

 

bindstaticfunc 

For static functions, the 'static_function_invoker' class in the parent will be called. The parent then needs to call GetStaticFunction() to find out the actual function to invoke.

ClosurePtr<> - Evil version
For compilers where data pointers are at least as big as code pointers, it is possible to store the function pointer in the this pointer, using another horrible_cast. Invocation isn't any faster, but it saves 4 bytes, and speeds up comparison and assignment. If C++ provided direct language support for delegates, they would produce asm code that was almost identical to this. Note that the Sun C++ and MSVC documentation explicitly state that they support static_cast between void * and function pointers. 

 

GetClosureMemPtr 

This is GetClosureMemPtr, a member of class ClosurePtr. 

 

GetClosureThis 

These functions are required for invoking the stored function 

 

GetStaticFunction 

 

 

IsEqualToStaticFuncPtr 

Does the closure contain this static function?
