Dear friends,

I assess my C++ knowledge as a beginner. I'm interested in doing systems programming. I have come across books called "C odyssey-Advanced Ms-DOS programming" and also "Writing TSRs through C" by kanetkar. Though those two books gave an idea of how viruses work by stealing system interrupts and replace them with their own.

The books were written for C and I couldn't find any book for writing TSRs in C++. Moreover somewhere i have read that for Windows environment(Multitasking environment) you can't write TSRs. Is it so?

Also in those books they described about far and huge pointers which are obsolete in C++. So my compiler(VC++) doesn't compile those programs. I couldn't do anything with this. Please help

is it possible to write TSRs in windows? Please throw some light on TSRs.

Regards
rmchokku.
