◆ DoRead()

FdReader::Data ns3::FdNetDeviceFdReader::DoRead ( )

overrideprivatevirtual

The read implementation.

The value of m_len returned controls further processing. The callback function is only invoked when m_len is positive; any data read is not processed when m_len is negative; reading stops when m_len is zero.

The management of memory associated with m_buf must be compatible with the read callback.

Returns: A structure representing what was read.

Implements ns3::FdReader.

◆ SetBufferSize()

void ns3::FdNetDeviceFdReader::SetBufferSize ( uint32_t bufferSize )

Set size of the read buffer.

Parameters

bufferSize the buffer size
