GenericInStream<STREAMBUF>&
getUint64(bsls::Types::Uint64& variable);Assign to the specified variable the eight-byte, two's complement unsigned integer (in host byte order) comprised of the eight bytes of this stream at the current cursor location (in network byte order), update the cursor location, and return a reference to this stream. If this stream is initially invalid, this operation has no effect. If this function otherwise fails to extract a valid value, this stream is marked invalid and the value of variable is undefined. Note that the value will be zero-extended.
