This function is not a Win32 API, but a function in Microsoft Visual
Studio's C library.

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.
