template< class MutableBufferSequence> std::size_t read_some( MutableBufferSequence const& buffers, error_code& ec);
This function is used to read some data from the underlying socket. The call blocks until one of the following is true:
|
Name |
Description |
|---|---|
|
|
The buffers into which the data will be read. If the size of the buffers is zero bytes, the call always returns immediately with no error. |

Set to indicate what error occurred, if any. |
The number of bytes read.
The read_some operation
may not receive all of the requested number of bytes. Consider using
the function net::read if you need to ensure that
the requested amount of data is read before the blocking operation completes.
