Functions
asnErr	asn1_decodeInteger (fpa1_syntaxList *listPtr, MHEG5Int *decodedInt)
	decodes Integer type
asnErr	asn1_decodeBoolean (fpa1_syntaxList *listPtr, MHEG5Bool *decodedBool)
	decodes Boolean type MHEG5TRUE and MHEG5FALSE macros are used for consistency. will default to MHEG5TRUE if it fails.
asnErr	asn1_decodeOctetString (fpa1_syntaxList *listPtr, MHEG5String *decodedString)
	decodes String type
asnErr	asn1_decodeColour (fpa1_syntaxList *listPtr, MHEG5Colour *colour)
	Decodes Colour class. Refer to MHEG5 Specification (ISO/IEC 13522-2:1996), Appendix A, section [A.43] for details of ASN.1 representation.

asnErr asn1_decodeBoolean	(	fpa1_syntaxList *	listPtr,
		MHEG5Bool *	decodedBool
	)

decodes Boolean type MHEG5TRUE and MHEG5FALSE macros are used for consistency. will default to MHEG5TRUE if it fails.

decodes Boolean type MHEG5TRUE and MHEG5FALSE macros are used for consistency. will default to MHEG5TRUE if it fails... is this safe???

Parameters:

listPtr	pointer to current fpa1_syntaxList item
decodedBool	Pointer to boolean type being decoded.

Returns:

asnErr

asnErr asn1_decodeColour	(	fpa1_syntaxList *	listPtr,
		MHEG5Colour *	colour
	)

Decodes Colour class. Refer to MHEG5 Specification (ISO/IEC 13522-2:1996), Appendix A, section [A.43] for details of ASN.1 representation.

Parameters:

listPtr	pointer to current fpa1_syntaxList item
colour	Pointer to Colour class being decoded.

Returns:

asnErr

asnErr asn1_decodeInteger	(	fpa1_syntaxList *	listPtr,
		MHEG5Int *	decodedInt

decodes Integer type

Parameters:

listPtr	pointer to current fpa1_syntaxList item
decodedInt	Pointer to integer type being decoded.

Returns:

asnErr

asnErr asn1_decodeOctetString	(	fpa1_syntaxList *	listPtr,
		MHEG5String *	decodedString
	)

decodes String type

Parameters:

listPtr	pointer to current fpa1_syntaxList item
decodedString	Pointer to string type being decoded.

Returns:

asnErr
