Detailed Description
Represents an IPv6 fragmentation extension header and allows easy access to all fragmentation parameters
Constructor & Destructor Documentation
◆ IPv6FragmentationHeader()
| pcpp::IPv6FragmentationHeader::IPv6FragmentationHeader | ( | uint32_t | fragId, |
| uint16_t | fragOffset, | ||
| bool | lastFragment | ||
| ) |
A c'tor for creating a new IPv6 fragmentation extension object not bounded to a packet. Useful for adding new extensions to an IPv6 layer with IPv6Layer::addExtension()
- Parameters
-
[in] fragId Fragmentation ID [in] fragOffset Fragmentation offset [in] lastFragment Indicates whether this fragment is the last one
Member Function Documentation
◆ getFragHeader()
|
inline |
Get a pointer to the fragmentation header. Notice the returned pointer points directly to the data, so every change will modify the actual packet data
- Returns
- A pointer to the ipv6_frag_header
◆ getFragmentOffset()
| uint16_t pcpp::IPv6FragmentationHeader::getFragmentOffset | ( | ) |
- Returns
- The fragment offset
◆ isFirstFragment()
| bool pcpp::IPv6FragmentationHeader::isFirstFragment | ( | ) |
- Returns
- True if this is the first fragment (which usually contains the L4 header), false otherwise
◆ isLastFragment()
| bool pcpp::IPv6FragmentationHeader::isLastFragment | ( | ) |
- Returns
- True if this is the last fragment, false otherwise
◆ isMoreFragments()
| bool pcpp::IPv6FragmentationHeader::isMoreFragments | ( | ) |
- Returns
- True if the "more fragments" bit is set, meaning more fragments are expected to follow this fragment
