Hello!
I've got the following problem:
I 'm a newbie to 32-Bit Dos-programming.
I transfer via DMA from a frame Grabber Card (BT848) to  memory that
is allocated by __dpmi_allocate_dos_memory(). 
This returns a DOS segment and a selector.
I want to port some image processing routines to DJGPP. These routines
use pointers to Bytes. 
To mimimize the porting effort, i want to create a pointer which
points to the memory allocated by __dpmi_allocate_dos_memory()
and can be used by the image processing routines.

I'd be happy if somebody could help.
