Pass a class as argument to a NSThread - c++

Question

How can I pass a class as argument to a thread using NSThread. In windows I was doing something like:
DWORD WINAPI threadFunc(LPVOID mpThis) {
MYCLSS *pThis = reinterpret_cast<MYCLSS*>(mpThis);
....
void MYCLSS::func() {
CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)threadFunc, (void*)this, 0, NULL);
....
For Mac I have not found any examples of this kind. Please help me

I found the solution, it can be like windows
class CLS_CPP {
public:
void Func();
void Check();
int var_check;
};
#interface CLS_OSX : NSObject {
#public
void *obj;
}
-(void)osx_thread;
#end
#implementation CLS_OSX
-(void)osx_thread {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
CLS_CPP *pThis = reinterpret_cast<CLS_CPP*>(obj);
pThis->Check();
NSLog(#"Check var %d", pThis->var_check);
[NSThread exit];
[pool drain];
}
#end
void CLS_CPP::Func() {
var_check=77;
CLS_OSX *trgt=[[CLS_OSX alloc] init];
trgt->obj=(void*)this;
[NSThread detachNewThreadSelector:#selector(osx_thread) toTarget:trgt withObject:trgt];
}
void CLS_CPP::Check() {
NSLog(#"CLS_CPP::Check success");
}
int main(int argc, char ** argv) {
CLS_CPP oAPP;
oAPP.Func();
}
