Hello... I was curious how I would get a segment:offset pair from a 32 bit address in djgpp? why you may ask? Because I need to get the segment:offset pair of a pointer to calculate it's 20 bit absolute address so I can use it in my sound routine(I'm *trying* to avoid using djgpp_near_pointer_enable();).... but being relativly new to protected mode programming I haven't a clue how to do this... for example.. i do this: unsigned char *buffer=(unsigned char *)calloc(64000,1); this gets me a pointer to a buffer...now what I need from the pointer is a segment:offset pair.....how would I do this? TIA. Derek
