If you are refering to hooking a vector so that you can call let's say one
program from another, you should have no problems.

If you just want to call the IV for some reason, don't.  I'ts not safe to
call those.  I used them quite a bit once when interfacing a C++ backend
database system with a turbo pascal front end in dos program.  One program
ran, installed the interrupt vector, then spawned the other program.

It's safe.

BTW I used interrupt 0x4c, or $4c (since I used both languages).


I wouldn't ever recommend anyone doing what I did, but I needed C++
templates for database lookups in a 200,000 line pascal program.   Needless
to say it worked.  Have fun!

(OH and don't mix 32bit and 16bit prot mode programs!!!! :)

Charles.
