I'm programming a CCD-Control program for a spectrograph.
The CCD is driven by giving the segment adress and the offset of the
pointer to
the command.

How can I get with djgpp these values from the pointer?
In Turbo-C and MicrosoftC it would work using
segment=FP_SEG( pointer)
offset=FP_OFF(pointer)
and
pointer=MK_FP(segment,offset).

Are there similar routines in the libraries or header-files?
Or do I have to write it in assembler (and how)?

Thanks a lot in advance,

Rivi
