Subject: resource_size doesn't change the resource
Date: Wed, 11 Nov 2009 15:04:24 +0100	[thread overview]
Message-ID: <20091111150424.37d56849@hyperion.delvare> (raw)

The resource_size function doesn't change the resource it operates on,
so the res parameter can be marked const. Same for the resource_type
function.
