/*! @file

This file test the PIN_InsertCallProbed feature.
|
|
The test application adds the special "annotations".
|
|
The test tool read the annotation and insert call to the notification function.
|
|
Since we want the notification prints to be interleaved with the application output,
|
|
we use the same "write function" from the application.
