What do you mean by "access" an interrupt? (Incindentally, int 0x10 is a BIOS
interrupt, not a DOS interrupt.)  If you mean "issue" an interrupt, the command
is just INT 10H (Intel format, I guess the AT&T format would be int $0x10).
If you want to intercept an interrupt, you use int 21h function 25h, set
interrupt vector (but first use function 35h get interrupt vector to save the
old one).

Yes, lots!  Check the libc docs.

Have fun!
Bill.
