* This pintool (atfork_callbacks.cpp) also prints numbers for the callbacks from PIN.

* The app (atfork_callbacks_app.cpp) also prints numbers for each of the pthreads callbacks.
|
|
*
|
|
* The before-fork callbacks are atfork_prepare() and pintool_on_fork_before()
|
|
* atfork_prepare() should precede pintool_on_fork_before()
|
|
*
|
|
* The after-fork callbacks for PARENT are atfork_parent() and pintool_on_fork_after_in_parent()
|
|
* pintool_on_fork_after_in_parent() should precede after-fork()
|
|
*
|
|
* The after-fork callbacks for CHILD are atfork_child() and pintool_on_fork_after_in_child()
|
|
* pintool_on_fork_after_in_child() should precede atfork_child()
