Changeset 98831 in vbox for trunk/src/VBox/Additions/common

Timestamp:

Message:

Guest Control: Made the directory entry reading really dynamic by letting the guest tell us the size it reports to the guest (limited by GSTCTL_DIRENTRY_MAX_SIZE). Re-introduced the #pragma pack(1) because we need the structures on mixed bitness (32 / 64 or vice versa) with the same size [build fix]. bugref:9783
