Read some data from the pipe.
template< typename MutableBufferSequence> std::size_t read_some( const MutableBufferSequence & buffers, boost::system::error_code & ec);
This function is used to read data from the pipe. The function call will block until one or more bytes of data has been read successfully, or until an error occurs.
One or more buffers into which the data will be read.
Set to indicate what error occurred, if any.
The number of bytes read. Returns 0 if an error occurred.
The read_some operation may not read all of the requested number of bytes.
Consider using the read
function if you need to ensure that the requested amount of data is read
before the blocking operation completes.
