Write a certain amount of data to a stream before returning.
template< typename SyncWriteStream, typename Allocator, typename CompletionCondition> std::size_t write( SyncWriteStream & s, basic_streambuf< Allocator > & b, CompletionCondition completion_condition);
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 one 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.
The basic_streambuf object from which data will be written.
The function object to be called to determine whether the write operation is complete. The signature of the function object must be:
bool completion_condition( const boost::system::error_code& error, // Result of latest write_some // operation. std::size_t bytes_transferred // Number of bytes transferred // so far. );
A return value of true indicates that the write operation is complete. False indicates that further calls to the stream's write_some function are required.
The number of bytes transferred.
Thrown on failure.
