The WWAN_SMS_STATUS structure represents the status of the SMS message store.
uFlagA 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).
MessageIndexThis 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.
