// DESCRIPTION: Indicates whether a piece of data is recognized as the protocol that the parser detects.
//
// ARGUMENTS: i_hFrame - The handle to the frame that contains the data.
// i_pbMacFrame - The pointer to the first byte of the frame; the pointer provides a way to view
// the data that the other parsers recognize.
// i_pbVoiceFrame - Pointer to the start of the unclaimed data. Typically, the unclaimed data is located
// in the middle of a frame because a previous parser has claimed data before this parser.
// i_dwMacType - MAC value of the first protocol in a frame. Typically, the i_dwMacType value is used
// when the parser must identify the first protocol in the frame. Can be one of the following:
// MAC_TYPE_ETHERNET = 802.3, MAC_TYPE_TOKENRING = 802.5, MAC_TYPE_FDDI ANSI = X3T9.5.
// i_dwBytesLeft - The remaining number of bytes from a location in the frame to the end of the frame.
// i_hPrevProtocol - Handle of the previous protocol.
// i_dwPrevProtOffset - Offset of the previous protocol (from the beginning of the frame).
// o_pdwProtocolStatus - Protocol status indicator. Must be one of the following: PROTOCOL_STATUS_RECOGNIZED,
// PROTOCOL_STATUS_NOT_RECOGNIZED, PROTOCOL_STATUS_CLAIMED, PROTOCOL_STATUS_NEXT_PROTOCOL.
// o_phNextProtocol - Placeholder for the handle of the next protocol. This parameter is set when the parser identifies
// the protocol that follows its own protocol.
// io_pdwptrInstData - On input, a pointer to the instance data from the previous protocol.
// On output, a pointer to the instance data for the current protocol.
//
// RETURNS: If the function is successful, the return value is a pointer to the first byte after the recognized parser data.
// If the parser claims all the remaining data, the return value is NULL. If the function is unsuccessful, the return
// value is the initial value of the i_pbVoiceFrame parameter.
