| struct _packet_info * | pinfo, | ||
| int | proto, | ||
| uint32_t | key, | ||
| void * | proto_data | ||
| ) |
Add data associated with a protocol.
This can be used to persist file-scoped data between packets or share packet-scoped data between dissectors without having to use global variables.
Each call adds a new entry to the protocol data list.
| scope | The memory scope, either pinfo->pool or wmem_file_scope(). |
| pinfo | This dissection's packet info. |
| proto | The protocol ID. |
| key | A unique key for the data. |
| proto_data | The data to add. |
| WS_DLL_PUBLIC void * p_get_proto_data | ( | wmem_allocator_t * | scope, |
| struct _packet_info * | pinfo, | ||
| int | proto, | ||
| uint32_t | key | ||
| ) |
Fetch data associated with a protocol.
| scope | The memory scope, typically pinfo->pool or wmem_file_scope(). |
| pinfo | This dissection's packet info. |
| proto | The protocol ID. |
| key | A unique key for the data. |
| WS_DLL_PUBLIC unsigned p_get_proto_depth | ( | struct _packet_info * | pinfo, |
| int | proto | ||
| ) |
Fetch the current per-protocol and per-packet recursion, nesting, or cycling depth.
| pinfo | Packet info for this packet. |
| proto | The current protocol. |
| WS_DLL_PUBLIC void p_remove_proto_data | ( | wmem_allocator_t * | scope, |
| struct _packet_info * | pinfo, | ||
| int | proto, | ||
| uint32_t | key | ||
| ) |
Remove data associated with a protocol.
| scope | The memory scope, typically pinfo->pool or wmem_file_scope(). |
| pinfo | This dissection's packet info. |
| proto | The protocol ID. |
| key | A unique key for the data. |
| WS_DLL_PUBLIC void p_set_proto_data | ( | wmem_allocator_t * | scope, |
| struct _packet_info * | pinfo, | ||
| int | proto, | ||
| uint32_t | key, | ||
| void * | proto_data | ||
| ) |
Set data associated with a protocol.
This can be used to persist file-scoped data between packets or share packet-scoped data between dissectors without having to use global variables.
If the protocol data list contains a matching entry it will be updated, otherwise a new entry will be created.
| scope | The memory scope, either pinfo->pool or wmem_file_scope(). |
| pinfo | This dissection's packet info. |
| proto | The protocol ID. |
| key | A unique key for the data. |
| proto_data | The data to add. |
| WS_DLL_PUBLIC void p_set_proto_depth | ( | struct _packet_info * | pinfo, |
| int | proto, | ||
| unsigned | depth | ||
| ) |
Initialize or update a per-protocol and per-packet check for recursion, nesting, cycling, etc.
| pinfo | Packet info for this packet. |
| proto | The current protocol. |
| depth | The depth to set. |
