Detailed Description

This class performs the actual data reading from the netmap ring.

Constructor & Destructor Documentation

◆ NetmapNetDeviceFdReader()

ns3::NetmapNetDeviceFdReader::NetmapNetDeviceFdReader ( )

Definition at line 89 of file netmap-net-device.cc.

References m_bufferSize, and m_nifp.

Member Function Documentation

◆ DoRead()

FdReader::Data ns3::NetmapNetDeviceFdReader::DoRead ( )

privatevirtual

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::NetmapNetDeviceFdReader::SetBufferSize ( uint32_t bufferSize )

Set size of the read buffer.

Parameters

bufferSize the size of the read buffer

Definition at line 97 of file netmap-net-device.cc.

References m_bufferSize, and NS_LOG_FUNCTION.

◆ SetNetmapIfp()

void ns3::NetmapNetDeviceFdReader::SetNetmapIfp ( struct netmap_if * nifp )

Set netmap interface representation.

Parameters

nifp	the netmap interface representation
