What system calls would I need to block totally, always allow or check the attributes of to: <ul> <li>Prevent forking or runing other commands</li> <li>Restrict to standard 'safe' C and C++ libs</li> <li>Prevent net access</li> <li>Restrict access to all but 2 files 'in.txt' and 'out.txt'</li> <li>Prevent access to any system functions or details.</li> <li>Prevent the application from escaping its supervisor</li> <li>Prevent anything nasty.</li> </ul> Thanks any help/advice/links much appreciated.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
