1) may throw std::ios_base::failure if an exception is thrown during output.. 2) may throw std::ios_base::failure if no characters are extracted from is (e.g the stream is at end of file, or consists of whitespace only), or if an exception is thrown during input. This class implements an extremely fast bulk output stream that can only output to a stream.. It does not support seeking, reopening, rewinding, line buffered disciplines etc.

Get/set content. The first form (1) returns a string object with a copy of the current contents of the stream. The second form (2) sets s as the contents of the stream, discarding any previous contents.
