Es gibt eine MacFUSE implementation of procfs. Mit ihm können Sie die Speicherkarte erhalten wie folgt:
cat /proc/PID/task/vmmap
Mit Blick auf die source code, es sieht aus wie es die Mach virtual memory interface ist mit der Speicherkarte aus dem Kernel zu bekommen.
Hier ist die Implementierung für die vmmap

Das ist wirklich gut aussieht, ich werde es wohl akzeptieren einmal laufe ich ein paar Tests, dass auf. – Sufian
