int 10h

[cman]

What interupts can be used in DOS box programs? I belive I've used a few in inline assembler for VC++ with no problems , but things like graphics interupts don't seem to work for me ( int 10h ). I was trying to write equivalents of Borlands gotoxy () , ect. functions when I found this is not I could'nt do this ( I know how to do this with console APIs , though ) . Thanks for any tips... :bg

It would depend on the version of Windows. Under Windows 9x any "normal" interrupt service should be fully functional. Under Windows NT/2000/XP I know that some of the system timer services do not work, and Interrupt 13h cannot access the hard disk drive, even for reading. AFAIK everything else should work OK. I can't recall ever seeing a problem with Interrupt 10h that could not be corrected with appropriate PIF settings.
