[comp.sys.apollo] Memory Protection on the Apollo

doray@crk45.bnr.ca (Bernard Doray 1632686) (01/11/90)

Is there an easy way to make a page in memory read-only under
Apollo Sr10.1?

(I want to detect if a procedure exceeds the stack space I have
allocated to it) 

the Mc68851 seems to allow that, but almost all the instructions 
for the Mc68851 are priviledged !! (not very convenient
since I want to make the program as safe as possible and easily
be able to ship it out to other nodes)

Thank you for your help.
