Description
1) Run cloneProcess
Your output should be (except for pids):
The variable was: 9
Part after clone has pid 10992
I am 10993 and my parent is 10992
The variable is now: 9
Read from the file: a
Explain why the file closure and the variable modification are not
recognized (variable has old value, and file still open).
2) Run cloneThread
Your output should be (except for pids):
The variable was: 9
Part after clone has pid 11051
I am 11052 and my parent is 11051
The variable is now: 42
File Read Error: Bad file descriptor
Explain why the file closure and the variable modification ARE
recognized (variable has new value, and file closed).
3) Copy file fork_mpm.c into a file named clone_mpmProcess.c
Modify clone_mpmProcess.c so that it accomplishes the same thing, but by using
clone instead of fork. Your output should be (except for pids):
> clone_mpmProcess
This is process(thread) 11501.
x+y=1
>
This is process(thread) 11502.
x+y=7
4) Copy clone_mpmProcess.c to clone_mpmThread.c and modify the latter so that
it spawns a thread (lightweight process) instead of a process.
Your output should be (except for pids):
> clone_mpmThread
This is process(thread) 11504.
x+y=1
>
This is process(thread) 11505.
x+y=8
