ns3::FdNetDeviceFdReader::FdNetDeviceFdReader ( )

Constructor for the FdNetDevice.

Definition at line 47 of file fd-net-device.cc.

Member Function Documentation

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

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.

A structure representing what was read.

Implements ns3::FdReader.
