Syntax
typedef struct _NDIS_WWAN_PREFERRED_PROVIDERS {

} NDIS_WWAN_PREFERRED_PROVIDERS, *PNDIS_WWAN_PREFERRED_PROVIDERS;
Members
Header
The header with type, revision, and size information about the NDIS_WWAN_PREFERRED_PROVIDERS structure. The MB Service sets the header with the values that are shown in the following table when it sends the data structure to the miniport driver for set operations. Miniport drivers must set the header with the same values when they send the data structure to the MB service.
| Header submember | Value |
|---|---|
| Type | NDIS_OBJECT_TYPE_DEFAULT |
| Revision | NDIS_WWAN_PREFERRED_PROVIDERS_REVISION_1 |
| Size | sizeof(NDIS_WWAN_PREFERRED_PROVIDERS) |
For more information about these members, see NDIS_OBJECT_HEADER.
uStatus
Miniport driver must set this to WWAN_STATUS_SUCCESS for unsolicited events (NDIS_STATUS_INDICATION::RequestId = 0). WWAN_STATUS_SUCCESS is also set for successful execution of the NDIS_WWAN_SET_PREFERRED_PROVIDERS.
The following table shows other possible error status codes (other members need not be updated by miniport driver).
| Value | Meaning |
|---|---|
| WWAN_STATUS_PIN_REQUIRED | Device requires PIN value input. |
| WWAN_STATUS_READ_FAILURE | Reading information from device or SIM card, or both, failed. For example, the SIM card does not have preferred providers information provisioned. |
| WWAN_STATUS_BAD_SIM | Bad SIM detected. |
| WWAN_STATUS_SIM_NOT_INSERTED | SIM not inserted in the device. |
| WWAN_STATUS_NO_DEVICE_SUPPORT | A set request is not supported. |
PreferredListHeader
A formatted WWAN_LIST_HEADER object that represents a list of preferred providers, including the number of providers in the list.
These point to the list of WWAN_PROVIDER2 by using the WWAN_LIST_HEADER structure. WwanDataClass flags describe the preference of the specific data access technology and can be set to any combination within its own cellular class.
Response to set OID_WWAN_PREFERRED_PROVIDERS requests must contain zero elements in the PreferenceListHeader.
Requirements
| Requirement | Value |
|---|---|
| Minimum supported client | Available in Windows 7 and later versions of Windows. |
| Header | ndiswwan.h (include Ndiswwan.h) |
