Why re-invent the wheel? Why don't you just use gdb?

the thing is we have to develop a debugger..
its kind of an assignment
i have downloaded the gdb source code
but its too huge to go thru it ..
i just want to know how i can set a breakpoint . is it using interrupts or exception

Homework assignments are not allowed on this forum, as per the forum rules.

Debuggers are very complicated programs, and if you don't know anything about Linux development, it seems that this is a poor program to attempt to design.

Having said that, if you're truly interested, gdb accomplishes what it does by using the ptrace system call. You may run the command "man ptrace" for more information.

If you eventually have more specific questions, please ask them.
