Getting Resource Sizes

The Resource Manager provides two routines that allow you to get the size of a
resource. The GetResourceSizeOnDisk and GetMaxResourceSize functions get the exact size and maximum size, respectively, of a resource. To change the size of a resource on disk, use the SetResourceSize procedure.
