Can a child process return a specific value to a parent process ?
Hello everybody !

I have two C source file: child.c and parent.c.

child.c looks like that:

Code:
int main()
{
...
return 15647
}

parent.c calls child using fork()-exec() or posix_spawn().
How can I get in parent the return code from child (here value is 15647) without using interprocess communication (pipe, shared memory, ...) ?
Is there any way to do that without IPC ?

Thank you !
