I am doing a frontend to an MSdos application, i.e. another msdos
application is started from my frontend, and I need to decode the
output from this application.

I think it is possible to trap a interrupt that accurs when a call to
printf is made, and then read the string a pointer is pointing to.

Could anyone tell me how to set up this trap, and what interrupt to use
and what the registers hold, or perhaps there are some good URL:s for
this ?

I program in djgpp.
