Detailed Description

This section documents the API of the ns-3 fd-net-device module.

For a generic functional description, please refer to the ns-3 manual.

Function Documentation

static void ns3::AddPIHeader ( uint8_t *&  buf,
size_t &  len 
)
static

Synthesize PI header for the kernel.

Parameters
bufthe buffer to add the header to
lenthe buffer length
Todo:
Consider having a instance member m_packetBuffer and using memmove instead of memcpy to add the PI header. It might be faster in this case to use memmove and avoid the extra mallocs.

Send the file descriptor back to the code that invoked the creation.

Parameters
pathThe socket address information from the Unix socket we use to send the created socket back to.
fdThe file descriptor we're going to send.
magic_numberA verification number to verify the caller is talking to the right process.
