GetDescription(const CSmsMessage &, TDes &, TInt)

IMPORT_C TInt	GetDescription	(	const CSmsMessage &	aMessage,
			TDes &	aDescription,
			TInt	aMaxLength = KSmsDescriptionLength
		)	[static]

Get the SMS message description.

If the message is Special Message Indication SMS then the description will contain the appropriate localised text for the indication.

If the message is a Status Report then the description will contain the appropriate localised text for a Status Report.

In all cases the buffer limit specified by aMaxLength is observered.

Parameters

const CSmsMessage & aMessage	The SMS message object.
TDes & aDescription	The output argument for the description.
TInt aMaxLength = KSmsDescriptionLength	The maximum length of the supplied buffer in aDescription.

			const CSmsMessage &	aMessage,
			TDes &	aDetails,
			TInt	aMaxLength = KSmsDetailsLength
		)	[static]

Get the SMS message recipient/sender details.

The recipient/sender telephone number is extracted from the supplied message object. If the recipient/sender telephone number appears uniquely in the contacts database then the family name and given name contact details are set into the output argument aDetails in the format specified by the resource item R_SENDER_NAME_FORMAT. The buffer limit specified by aMaxLength is observed.

If there is not a unique contact entry for the recipient/sender telephone number then aDetails will contain the orginally telephone number.

Parameters

			const TDesC &	aFromAddress,
			TDes &	aDetails,
			TInt	aMaxLength = KSmsDetailsLength
		)	[static]

Get the SMS message recipient/sender details.

The recipient/sender telephone number is searched for in the contacts database. If a unique match is found then the family name and given name contact details are set into the output argument aDetails in the format specified by the resource item R_SENDER_NAME_FORMAT. The buffer limit specified by aMaxLength is observed.

If a unique match is not found or the supplied telephone number is invalid, then aDetails will contain the orginally telephone number.
