NAME
    RISCOS::ValidateAddr -- perl module that checks an address range
    is valid

SYNOPSIS
        use RISCOS::ValidateAddr;
        $is_valid = validate_addr ($lower_inc, $upper_exc);


DESCRIPTION
    This module provides a perl interface to `OS_ValidateAddress'.
    This checks the address range between the lower (inclusive) and
    upper (exclusive) bounds to see if the entire specified range
    maps into physical RAM or ROM. (The memory should actually exist
    unless you've been fiddling with `OS_SetMemMapEntries'.)

    Returns `2' if the address range is in ROM, `1' if the address
    range is valid as RAM, `0' if it is not, undefined on error.
