Does anyone know about how to port the Windows programs to MetaWare compiler
for 32-bit environment (of course, still running under Windows 16-bit
environemnt). I have trouble to use the GlobalAlloc & GlobalLock. Because
the MetaWare include a NEW windows.h that declare FAR as "". (nothing)

How to change my program without pain? By the way, no matter what the Local
or Globle memory API used, I always got a compiler waring like that:

"far pointer address truncated to near pointer"

Why? especially in GlobalLock and LocalLock!?


Any suggestion will be very appreciated,

The MetaWare ADK converts the results of GlobalLock and LocalLock to
32-bit Far pointers. What you really want to do is switch to malloc
if you're writing C or new if you're writing C++.

Note that near 32-bit pointers (as returned by malloc or new) give you
the full speed you wanted when you went to 32-bit integers to begin with.
Far 32-bit pointers are just as slow as far 16-bit pointers.
