Question

A friend sent me his threading class.
Now I just want to run a listener but the thread doesnt want to accept the function.
I want to execute the function (defined in static class Networks) THREAD listen(void* args). THREAD is a #define THREAD unsigned __stdcall

Networks::init() {
  listenerth = thread();
  listenerth.run(listen, NULL, "listener");
}

In class thread he defined run as void run( THREAD func(void*), void* args, const char* pname);

How can I get that to run listen in another thread either?

[edit]
Error message:
main.cpp(19): error C3867: ‘Networks::listen’: function call missing argument list; use ‘&Networks::listen’ to create a pointer to member

But when i move my mouse to the error place(symbol listen), it shows me this in a tooltip(yes, MS VC++):

unsigned int __stdcall
Networks::listen(void* data)

Error: argument of type “unsigned int
(__stdcall Networks::*)(void *data)”
is incompatible with parameter of type
“unsigned int (__stdcall )(void)”

As others say, you can’t use a non-static member function here, because it expects a normal function pointer. If you need to call a non-static member (because it needs to access state in the class), then you could use the args argument to call it via a static “trampoline” function, something like this:

unsigned listen() {/* do the interesting stuff */}

static THREAD call_listen(void* me) 
{
    return static_cast<Networks*>(me)->listen();
}

void init()
{
    listener = thread();
    listener.run(call_listen, this, "listener");
}
