MFileSystemClusterSize Class Reference

class MFileSystemClusterSize

MFileSystemClusterSize interface provides extended interface for CMountCB to retrieve cluster size of mounted file systems.

The interface could be retrieved by calling CMountCB::GetInterface() with EGetClusterSize as an argument.

If the file system does not support clustering, MFileSystemClusterSize cannot be retieved. Sub classes of CMountCB who does support clustering will need to multiple-inherit with this class and implement the interface. The implementation of the interface will be retrieved via GetInterface() and provided to user by non-virtual APIs to avoid breaking binary compatibility.

NOTE: Do not try to delete MFileSystemSubType interface pointer!
