Title: How to debug the "fork()" program?
Post by: gonboy on August 13, 2008, 03:03:15 am

1 -    You can get  the return value of fork(),so you can debug it. eg pid = 0, in the children process, pid >0 ,in the father process.

        But if I want to debug the father and children process at the same time ,how to do?

2 -    How do you know which process will be run ? why?

The fork method is very problematic. Why can't it work fine like any other compiler?????

Compiler or debugger?

As far as I know forks works perfectly using gcc as compiler.
And here is some info related to the debugger: http://sourceware.org/gdb/onlinedocs/gdb/Forks.html

I'm not sure if gdb supports debugging both parent and child, I've not read the above page  :lol: :P
