HI!
I have a very urgent request for help concerning Microsoft C/
Quick C, Ms-Dos and INT 24 Failures.
Working for BT I have come across a need to write a database system with
a fair degree of disk access. However, I need either a method of
formatting the stderr stream or a method of replacing the INT 24 vector
with one of my own.
I'd prefer a vector redirection based solution, but I cannot for the life of me
get the program to work as it should (it compiles..)
At present I am (have tried) copying the old interrupt vector
so it can be restored later , then substituting my own vector address
pointing to a simple routine that simple returns, maybe printing an error
message first.
Even compiling without the stack checking (as required in the Turbo C
environment) the program seems to either ignore my interrupt vector
completely, or executes my routine then freezes.
All I need is something that will return a value of zero somehow without
the humungous error messages that usually occur, and without the
press so and so to continue or abort etc...
If ya can help email me as soon as you can...This database has to be finished
soon. Ack. You could say the critical errror handler has gone critical.
Many thanks,
Ian Coggins,
Comp systems Engineer.
