bdexStreamIn(

    int version);

Description

Assign to the specified variable the VALUE_TYPE value read from the specified input stream using the specified version format, and return a reference to stream. If stream is initially invalid, this operation has no effect. If version is not supported by VALUE_TYPE, variable is unaltered and stream is invalidated, but otherwise unmodified. If version is supported but stream becomes invalid during this operation, variable has an undefined, but valid, state. See the bslx package-level documentation for more information on BDEX streaming of value-semantic types and containers.
