I found that in windowsx.h of cygwin/gcc there are the following functions defined:

#define GlobalAllocPtr(flags,cb) (GlobalLock(GlobalAlloc((flags),(cb))))
#define GlobalFreePtr(lp) (GlobalUnlockPtr(lp),(BOOL)GlobalFree(GlobalPtrHandle(lp)))

May these functions also be used for copying a string? How must they be used? (Maybe this works also for string > 64 KB?!)
Is this also a way for interworking of Borland and Visual?
