WWAN_SMS_PDU_RECORD structure (wwan.h)

The WWAN_SMS_PDU_RECORD structure represents a PDU-style SMS message record.

Syntax

typedef struct _WWAN_SMS_PDU_RECORD {
  ULONG           MessageIndex;
  WWAN_MSG_STATUS MsgStatus;
  BYTE            Size;
  CHAR            PduData[WWAN_SMS_PDU_HEX_BUF_LEN];
} WWAN_SMS_PDU_RECORD, *PWWAN_SMS_PDU_RECORD;

Members

MessageIndex

An index into the virtual message store that is maintained by the miniport driver. This index is 1-based and the maximum index is ulMaxMessageIndex returned in WWAN_SMS_CONFIGURATION_STATUS. Be aware that the specification does not differentiate between physically available data stores. If the message is a Class 0 (flash/alert) message, this must be set to WWAN_MESSAGE_INDEX_NONE.

MsgStatus

The status of the record that represents whether the SMS message is new (unread), old (read), a draft, or sent.

Size

The size, in bytes, of the record.

For GSM-based devices, this represents the size of the message before conversion to a hexadecimal string.

For CDMA-based devices, this represents the number of bytes in the PduData .

PduData[WWAN_SMS_PDU_HEX_BUF_LEN]

For GSM-based devices, a NULL-terminated string that contains the content of the record coded in a hexadecimal string format (according to the 3GPP TS 27.005 and 3GPP TS 23.040 standards) that represents the SMS message.

For CDMA-based devices that support reading SMS messages in binary format (as returned in WWAN_SMS_CAPS as WWAN_SMS_CAPS_PDU_RECEIVE) this member contains the SMS message as a byte array, as defined in section 3.4.2.1 SMS Point-to-Point Message in 3GPP2 specification C.S0015-A "Short Message Service (SMS) for Wideband Spread Spectrum Systems". SMS will only support Wireless Messaging Teleservice (WMT) format. Miniport drivers should typecast this information to BYTE[] for CDMA-based devices. It is not coded in hexadecimal string format. The message is not NULL-terminated.
