The ByVal and ByRef operators don't exist in VFP, there is no ANY type, but you can simulate a buffer with a string. I would not recommend using an overlapped structure; instead, I'd declare it as an integer type and pass 0 to represent a null pointer.

Try:

DECLARE INTEGER GetStdHandle IN KERNEL32.DLL INTEGER nStHandle
DECLARE INTEGER ReadFile IN WIN32API ;
  INTEGER hFile, ;
  STRING @ lpBUffer, ;
  INTEGER nBytesToRead, ;
  INTEGER nBytesActuallyRead, ;
  INTEGER lpOverlapped
LOCAL hStdOut, hStdIn, cBuff, nBytesRead, nResult
hStdOut = GetStdHandle(-11)
hStdIn = GetStdHandle(-10)
cBuff=SPACE(256)
nBytesRead = 0
nResult = ReadFile(hStdIn, ;
                   @cBuff, ;
                   256, ;
                   @nBytesRead, ;
                   0)

>PUBLIC hnSTDOUT,hnSTDIN

Don't use PUBLICs if you can avoid it. There is just too much wierdness, and it's bad OOP. If a function, procedure or method need them, pass them to whatever needs the values, or stick them in properties of a known object.

>hnSTDOUT=GetStdHandle(@STD_OUTPUT_HANDLE)

You can't pass a constant by reference. You'd have to #DEFINE STD_OUTPUT_HANDLE or it must be in a file in a #INCLUDE. For brevity, i just used the constants defined in WINBASE.H directly.

This code is untested; I did it off the top of my head. It's generally correct but it hasn't been checked for typos or against the declarations in the MSDN docs.
