Q.  How can I get a Windows HANDLE for stdin or stdout?

A.  Here's how:

	#include <stdio.h>

	HANDLE	hStdIn, hStdOut;

	hStdIn = GetStdHandle(STD_INPUT_HANDLE);
	hstdOut = GetStdHandle(STD_OUTPUT_HANDLE);

	or:

   	hStdIn = (HANDLE) _get_osfhandle(fileno(stdin));
	hStdOut = (HANDLE) _get_osfhandle(fileno(stdout));

	// Now you can use hStdIn and hStdOut in regular win32 function like:

	GetFileInformationByHandle(hStdIn, &info);

	GetFileSizeEx(hStdOut, &li);

	type = GetFileType(hStdIn);

	...
