Unlike UNIX-like systems, Windows does not have the equivalent of a C library for providing run-time support to C programs (malloc, printf, etc). C programming environments targetting Windows have to provide their own. _beginthreadex is a wrapper for CreateThread which routes the thread through a startup function within the C library, where it can initialize some thread-local storage specific to that library and whatnot. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
