The following helper functions are called by parsers.
| Function | Description |
|---|---|
| AddressToString | Converts an address to a string. |
| LookupByteSetString | Retrieves the string corresponding to the specified value of a labeled set. |
| SetCCInstPtr | Captures a context instance pointer. |
| StringToAddress | Converts a string to an address. |
| VarLenSmallIntToDword | Converts a variable-length, small integer to a DWORD. |
| LookupDwordSetString | Retrieves the string corresponding to the specified value of a labeled set. |
| LookupWordSetString | Retrieves the string corresponding to the given value from a labeled set. |
| BERGetHeader | Decodes a choice header. |
| BERGetInteger | Decodes a BER-encoded integer. |
| BERGetString | Decodes a BER-encoded string. |
| CCHeapAlloc | Allocates memory on a capture-by-capture basis. |
| CCHeapFree | Releases the memory allocated by the CCHeapAlloc function. |
| CCHeapReAlloc | Reallocates memory allocated by the CCHeapAlloc function. |
| CCHeapSize | Retrieves the size of the memory allocated by the CCHeapAlloc function. |
| GetCCInstPtr | Retrieves the pointer to the instance data added to the capture context. |
| CreateProtocol | Informs the Network Monitor API that a specific protocol parser exists. |
| DestroyProtocol | Destroys the protocol created by the CreateProtocol function. |
| BuildINIPath | Retrieves a fully qualified path to the initialization (INI) file that corresponds to information you enter. |
| CreateHandoffTable | Creates a handoff table based on information in an given INI file. |
| DestroyHandoffTable | Destroys a handoff table created with the CreateHandoffTable function. |
| GetProtocolFromTable | Retrieves the protocol of a given handoff table. |
| AddProperty | Adds a PROPERTYINFO structure to the property database. |
| AttachPropertyInstance | Attaches a property instance to a frame. |
| AttachPropertyInstanceEx | Attaches a property instance to a frame. |
| CreatePropertyDatabase | Creates a property database that describes properties that the parser uses to describe its data. |
| DestroyPropertyDatabase | Destroys a property database created by calls to the CreatePropertyDatabase and AddProperty functions. |
| FindNextFrame | Finds the next frame in the current capture context that matches a given filter. |
| FindPreviousFrame | Finds the previous frame in the current capture context that matches a given filter. |
| FormatPropertyInstance | Formats the property instance in a generic manner. |
| GetFrameDestAddress | Retrieves the destination address of a frame. |
| GetFrameSourceAddress | Retrieves the source address of a frame. |
| GetProtocolStartOffset | Retrieves the offset to a given protocol in the frame. |
| ParserTemporaryLockFrame | Locks a frame when it enters a parser and unlocks the frame when it exits. |
