For debugging purpose, I want something like 'getchar()' that can pause execution in the module code. Do any candidates I can choose?
The problem is that pausing execution in module code is dangerous, as if you hold any locks or anything like that, you can hang other threads or even the whole machine. You probablhy want to be looking at the kgdb support, that is coded to work around a lot of the issues and you get full GDB support not just a getchar() pause.
