Detailed Description
Represents a NULL/Loopback layer
Constructor & Destructor Documentation
◆ NullLoopbackLayer() [1/2]
|
inline |
A constructor that creates the layer from an existing packet raw data
- Parameters
-
[in] data A pointer to the raw data [in] dataLen Size of the data in bytes [in] packet A pointer to the Packet instance where layer will be stored in
◆ NullLoopbackLayer() [2/2]
| pcpp::NullLoopbackLayer::NullLoopbackLayer | ( | uint32_t | family | ) |
A constructor that allocates a new Null/Loopback header
- Parameters
-
[in] family The family protocol to set
◆ ~NullLoopbackLayer()
|
inline |
A destructor for this layer (does nothing)
Member Function Documentation
◆ computeCalculateFields()
|
inlinevirtual |
Does nothing for this layer
Implements pcpp::Layer.
◆ getFamily()
| uint32_t pcpp::NullLoopbackLayer::getFamily | ( | ) |
- Returns
- The protocol family in this layer
◆ getHeaderLen()
|
inlinevirtual |
- Returns
- Size of Null/Loopback header = 4B
Implements pcpp::Layer.
◆ getOsiModelLayer()
|
inlinevirtual |
- Returns
- The OSI Model layer this protocol belongs to
Implements pcpp::Layer.
◆ parseNextLayer()
|
virtual |
Identifies the next layers by family:
- for PCPP_BSD_AF_INET the next layer is IPv4Layer
- for PCPP_BSD_AF_INET6_BSD, PCPP_BSD_AF_INET6_FREEBSD, PCPP_BSD_AF_INET6_DARWIN the next layer is IPv6Layer
- for other values the next layer in PayloadLayer (unknown protocol)
Implements pcpp::Layer.
◆ setFamily()
| void pcpp::NullLoopbackLayer::setFamily | ( | uint32_t | family | ) |
Set a protocol family
- Parameters
-
[in] family The family protocol to set
◆ toString()
|
virtual |
- Returns
- A string representation of the layer most important data (should look like the layer description in Wireshark)
Implements pcpp::Layer.
