WWAN_SMS_STATUS structure (wwan.h)

The WWAN_SMS_STATUS structure represents the status of the SMS message store.

Syntax

typedef struct _WWAN_SMS_STATUS {
  ULONG uFlag;
  ULONG MessageIndex;
} WWAN_SMS_STATUS, *PWWAN_SMS_STATUS;

Members

uFlag

A bitmap of flags that represent the status of the message store on the MB device. The values for uFlag are defined in the following table.

Value	Meaning
WWAN_SMS_FLAG_NONE	No status to report.
WWAN_SMS_FLAG_MESSAGE_STORE_FULL	The message store is full.
WWAN_SMS_FLAG_NEW_MESSAGE	A new, non-Class 0 (flash/alert) message has arrived.

 

Miniport drivers should not set or clear any flag until a change of state occurs. For example, the WWAN_SMS_FLAG_MESSAGE_STORE_FULL flag must remain set until the miniport driver completely processes a delete message request that comes from the MB Service. Similarly, the WWAN_SMS_FLAG_NEW_MESSAGE flag must remain set until the miniport driver completely processes a read new message request from the MB Service.

Miniport drivers must send an unsolicited event to the MB Service whenever a flag is set. Miniport drivers do not need to send an unsolicited event when a flag is cleared (reset).

MessageIndex

This is the index of the newly arrived message or the recently arrived message in case of a query response.

Unique index into the message store between 1 and ulMaxMessageIndex returned in NDIS_STATUS_WWAN_SMS_CONFIGURATION.

If the uFlag is not set with WWAN_SMS_NEW_MESSAGE, this member must be initialized by the miniport driver with WWAN_MESSAGE_INDEX_NONE.
