Detailed Description

Defines abstract BDataIO and BPositionIO and the derived BMallocIO and BMemoryIO classes.

Pure virtual BDataIO and BPositioIO classes provide the protocol for Read(), Write(), and Seek().

BMallocIO and BMemoryIO classes implement the protocol, as does BFile in the Storage Kit.
