But now I cant call non-static member function of the same class from the thread function:

c:\t\cpp\killbot\bot.cpp(124) : error C2352: 'CBot::Connect' : illegal call of non-static member function
        c:\t\cpp\killbot\bot.h(32) : see declaration of 'Connect'

I managed to get it to work another way by having it as a global friend function of the class, and passing a pointer to the class as the paramater:

CBot class
{

friend void* Main(void* pData);


bool OtherMemberFunction();
}

void* Main(void* pData)
{
 CBot* pBot = (CBot*)pData;

 pBot->OtherMemberFunction();
}



Suggest any better way?

why the routine of pthread_create should be a static function:

in compilation time, the compiler need an address of the routine, non static
function has no address in the compilation time. i.e., address of automatic
class member function is resolved in run time.

Also, see/join "CUJ/"The Boost.Threads Library"
article - feedback/comments?!" comp.programming.threads
discussion; well, I've just recenly posted that message/
call for comments/feedback... so, there is no much of the
"discussion" yet. But, hey, folks, why don't you also join
and share your opinions... with respect to that "boost.org's"
partial/incomplete/buggy-not-fully-complient/poor/etc
*pthreads-win32 "FORK"* (LGPL -> no-restrictions/free
"relaxation" aside)?!?!?!

[Bossom, John]

simply have your class have a static member function that you use as the
mainline
instead of a friend class and do the same as your example below.
