Probing for (non-existing) memory?

[Wolfgang Denk]

Hi,

please excuse the silly question: is there a standard way to probe an
address if it is readable/writable memory? Ideally something that  is
portable across all architectures?

[For those familiar with LynxOS: what I'm looking  for  is  something
like recoset() / noreco().]

Thanks in advance,

Wolfgang Denk
