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
