bdexStreamIn(
STREAM& stream,
bsls::Types::Int64& variable,
int version = 0);Assign to the specified variable the bsls::Types::Int64 value read from the specified input stream, and return a reference to stream. The optionally specified version is ignored. If stream is initially invalid, this operation has no effect. If 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.
