##### basic_stream_file::write_some (2 of 2 overloads)

Write some data to the file.

    template<
        typename ConstBufferSequence>
    std::size_t write_some(
        const ConstBufferSequence & buffers,
        asio::error_code & ec);

This function is used to write data to the stream file. The function call will block until one or more bytes of the data has been written successfully, or until an error occurs.

###### Parameters

buffers

  One or more data buffers to be written to the file.

ec

  Set to indicate what error occurred, if any.

###### Return Value

The number of bytes written. Returns 0 if an error occurred.

###### Remarks

The write_some operation may not transmit all of the data to the peer. Consider using the `write` function if you need to ensure that all data is written before the blocking operation completes.
