RMsvReadStream Class Reference

class RMsvReadStream : public RReadStream

Accesses the streams in a message store with read access.

Before it is used, a CMsvStore must have been opened on the message store with read or read/write access.

This class is intended for use by MTM implementations to store MTM-specific information. Message client applications access the store through the higher-level functions provided by Client-side and User Interface MTMs.

Most of its functionality is provided by the base class RReadStream .
