2.1.4.7 ClustersFromBytes -- Macro to Determine How Many Clusters a Given Number of Bytes Occupies

  • Article

The inputs for this algorithm are:

  • ThisVolume: A Volume.

  • Bytes: The number of bytes.

Pseudocode for the algorithm is as follows:

  • ClustersFromBytes(ThisVolume, Bytes) = (Bytes + (ThisVolume.ClusterSize - 1)) / ThisVolume.ClusterSize.

  • The value returned is the total number of clusters required to hold the specified number of bytes that start at a cluster boundary, including any remainder that does not fill a whole cluster.
