How do I create a thread routine of a static member function

Answer 1

Sometimes, it is useful to read the error you're getting.

cannot convert parameter 3 from 'void (void)' to 'unsigned int (__stdcall *)(void *)'

Let's look at what it says. For parameter three, you give it a function with the signature void(void), that is, a function which takes no arguments, and returns nothing. It fails to convert this to unsigned int (__stdcall *)(void *), which is what _beginthreadex expects:

It expects a function which:

• Returns an unsigned int:
• Uses the stdcall calling convention
• Takes a void* argument.

So my suggestion would be "give it a function with the signature it's asking for".

class Blah
{
    static unsigned int __stdcall Start(void*);
};
