This code does not and SHOULD not check whether the contents of the region are accessible. For example, a small file may be mapped into an address space which is significantly larger in size.RETURN VALUES
The Fn vm_map_check_protection function returns TRUE if the privilege is allowed; if it is not allowed, or if any other error occurred, the value FALSE is returned.SEE ALSO
