safe_address

include std/machine.e 
public function safe_address(machine_addr start, natural len,  
              positive_int action ) 

action is some bitwise-or combination of the following constants: A_READ, A_WRITE and A_EXECUTE.

Returns:

When Safe Mode is turned on, this returns true iff it is ok to perform action all addresses from start to start+len-1.

When Safe Mode is not turned on, this always returns true.

Comments:

This is used mostly inside the safe library itself to check whenever you call Machine Level Access Functions or Procedures. It should only be used for debugging purposes.
