You'd get better responses on the MinGW list.

For this you need to use the Win32 API.  See for example
CreateWaitableTimer(), SetWaitableTimer(), WaitForSingleObject(),
CreateThread/_beginthreadex and so on.  See MSDN for details, or the

These are the APIs provided by the operating system; they have nothing
to do with Visual C++.  The w32api package includes all the import
