Passing functions by value in a class...

[Sebastiani]

c:\I.cpp: In method `bool InputBuffer::Create(long unsigned int = 10000)':
c:\I.cpp: 73: no matches converting function `Thread' to type `DWORD (*)(void *)'
c:\I.cpp: 31: candidates are: DWORD InputBuffer::Thread(void *)

The problem is when I pass a certain function by address into another function in a class, the compiler won't allow it.
Yet when I call the same function in a straight C program, it allows it to compile and the function runs smoothly.

...any ideas?

I know that the type-checking is tighter with C++, but this is ridiculous.

THREAD
NewThread( DWORD func(LPVOID), LPVOID params, DWORD *id = NULL)
{
static DWORD fakeIt = 0;

if(id == NULL)
{
fakeIt++;
id = &fakeIt;
}
return CreateThread(NULL, 0, func, params, 0, id);
}








//...hypothetical.cpp //...runs fine

THREADFUNC s(LPVOID d){return 0;}





int main(int argc, char *argv[])
{
char c = 's';

THREAD t = NewThread(s, &c);

while(ThreadIsActive(t)); //...wait...

return 0;
}

Is THREADFUNC the same as DWORD?

If think it should be something like this (did not test it):

NewThread( DWORD (*func)(LPVOID), LPVOID params, DWORD *id = NULL)

No, it is a typedef for DWORD WINAPI. I am reading all about it now. It was because of some very partcular class restrictions which will require a slight rewrite....more later, thx
