Memory Reading/Writing causes seg fault

[sean04]

I wanted to know if there is a system call that will determine if a process will cause a segmentation fault when trying to read/write to a particular memory address.

I seriously doubt it, because it's rare, if ever, that a system call exists to do something you can do yourself in userland.

And you can find out without a special system call whether a given address is in your address space.

Do this at the command line:

man proc

and search for maps, and all will be revealed.
