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.
