Perché /proc/pid/maps
contiene alcuni record per la stessa libreria? Ecco un esempio:
7fae7db9f000-7fae7dc8f000 r-xp 00000000 08:05 536861 /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.20
7fae7dc8f000-7fae7de8f000 ---p 000f0000 08:05 536861 /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.20
7fae7de8f000-7fae7de97000 r--p 000f0000 08:05 536861 /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.20
7fae7de97000-7fae7de99000 rw-p 000f8000 08:05 536861 /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.20
Cosa significa questo ?
