how to set breakpoint and show source code when us

Question

why bp main failed? how to list source code as gdb's list command does?

this question is not the same as CDB command for setting a breakpoint based on a line number

seems cdb can be used with windbg, but is that possible to use cdb a bit similar to gdb?

Answer 1

cdb allows 3 different commands to set breakpoints: bp, bm, and bu

1. bp accepts arguments that are numeric addresses
2. bm accepts arguments that are textual symbols in a module that is already loaded
3. bu accepts arguments that are textual symbols in modules that may or may not be loaded yet.

To Set a breakpoint at main we can guess Image00390000 is actually hello.exe (Sometimes cdb fails to recover the name you would expect). You can use the command:

bm Image00390000!main

This assumes that main really is the symbol name, and that symbols are loaded. You can use:

lmvm Image00390000 //to check if symbols are loaded
x Image00390000!*main* //lists all symbols that have main anywhere in the name
