How does fork() return for child process
- by EpsilonVector
I know that fork() returns differently for the son and father processes, but I'm unable to find information on how this happens. How does the son process receive the return value 0 from fork? And what is the difference in regards to the call stack? As I understand it, for the father it goes something like this:
father process--invokes fork--system_call--calls fork--fork executes--returns to--system_call--returns to--father process.
What happens in the son side?
