Read-only memory on x86?

Read-only memory on x86?

[A Dell'elce]

Probably it is somewhere hidden on a faq.. but I will ask 
again ...

Can I set a memory area or "page" to be read-only, i.e. 
generate an interrupt when writing is attempted to a certain 
page/area?


 Thanks, Antonio

man mmap and catch SIGSEGV. Or see how the DOSemu VGA emulator
manipulates the virtual VGA memory.
