Extract an array of eight-byte IEEE doubles from this stream.

GenericInStream<STREAMBUF>&
getArrayFloat64(
double* variables,
int numVariables);Assign to the specified variables the consecutive eight-byte IEEE double-precision floating-point numbers (in host byte order) comprised of each of the specified numVariables eight-byte sequences 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 variables is undefined. The behavior is undefined unless 0 <= numVariables and variables has sufficient capacity.
