template< class ConstBufferSequence> std::size_t put( ConstBufferSequence const& buffers, error_code& ec);
This function attempts to incrementally parse the HTTP message data stored in the caller provided buffers. Upon success, a positive return value indicates that the parser made forward progress, consuming that number of bytes.
In some cases there may be an insufficient number of octets in the input
buffer in order to make forward progress. This is indicated by the code
error::need_more. When this happens, the caller should place additional
bytes into the buffer sequence and call
The error code error::need_more is special. When this error is returned,
a subsequent call to
http::basic_parser::put may succeed if the buffers
have been updated. Otherwise, upon error the parser may not be restarted.
An object meeting the requirements of ConstBufferSequence that represents the next chunk of message data. If the length of this buffer sequence is one, the implementation will not allocate additional memory. The class flat_buffer is provided as one way to meet this requirement
Set to the error, if any occurred.
The number of octets consumed in the buffer sequence. The caller should remove these octets even if the error is set.
