Hi,
is it possible to create a static buffer (array of few megs) which can
be accessed both by a DJGPP program running under NTVDM of WinNT/XP
and console win32 application compiled in MinGW32? I would imagine
that in DJGPP I will read current DS, look to LDT which is the base of
the DS selector and some way forward this base + offset to buffer to
win32 app. It will create its own local selector with this base+offset
and will read from there. But I don't know if it would be possible
from user program or I would need some KMD which will be called
through IOCTL - bleh big overhead.
Or would it be possible to do it from other side? Allocate buffer in
win32 app and acces it from DJGPP program?
Any idea?
