Detailed Description

Radiotap header implementation.

Introspection did not find any typical Config paths.

Radiotap is a de facto standard for 802.11 frame injection and reception. The radiotap header format is a mechanism to supply additional information about frames, from the driver to userspace applications such as libpcap, and from a userspace application to the driver for transmission.

No Attributes are defined for this type.
No TraceSources are defined for this type.
Size of this type is 64 bytes (on a 64-bit architecture).

void ns3::RadiotapHeader::Print ( std::ostream & os ) const

virtual

This method is used by Packet::Print to print the content of the header as ascii data to a C++ output stream.

Although the header is free to format its output as it wishes, it is recommended to follow a few rules to integrate with the packet pretty printer: start with flags, small field values located between a pair of parens. Values should be separated by whitespace. Follow the parens with the important fields, separated by whitespace.

eg: (field1 val1 field2 val2 field3 val3) field4 val4 field5 val5

Parameters

os	The output stream

Implements ns3::Header.

void ns3::RadiotapHeader::Serialize ( Buffer::Iterator start ) const

virtual

This method is used by Packet::AddHeader to store the header into the byte buffer of a packet.

The data written is expected to match bit-for-bit the representation of this header in a real network.

Parameters

start An iterator which points to where the header should be written.

Implements ns3::Header.
