Write all of the supplied data to a stream before returning.
template< typename SyncWriteStream, typename Allocator> std::size_t write( SyncWriteStream & s, basic_streambuf< Allocator > & b);
This function is used to write a certain number of bytes of data to a stream. The call will block until one of the following conditions is true:
This operation is implemented in terms of zero or more calls to the stream's write_some function.
The stream to which the data is to be written. The type must support the SyncWriteStream concept.
basic_streambuf object from
which data will be written.
The number of bytes transferred.
Thrown on failure.
