[gameprogrammer] Re: Multi-Threading in C++

Hi,

DO NOT use CreateThread() unless you are aware of its shortcomings.

http://msdn2.microsoft.com/en-us/library/ms682453.aspx

"A thread in an executable that calls the C run-time library (CRT) should use
the _beginthreadex and _endthreadex functions for thread management rather than
CreateThread and ExitThread; this requires the use of the multi-threaded version
of the CRT. If a thread created using CreateThread calls the CRT, the CRT may
terminate the process in low-memory conditions."

Cheers,
Paulo
