Function: DecodeL,

: Decodes SUPL message. The parameters to decode message are encoded message, error code to be returned and the number of bytes to be decoded.

: aPacket , Encoded SUPL message : aErrorCode , Upon completion contains the result of decoding : aUnConsumedBytes , Unconsumed bytes in the encoded message

: Pointer to decoded SUPL message

Parameters
