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.
