This function gets the minimum quality of service profile for all contexts.

Syntax

HRESULT RIL_GetMinimumQualityOfServiceList(
  HRIL hRil
  RILGPRSQOSPROFILE * lpGprsQosProfile,
  DWORD * pdwDataSize
);

Parameters

  • lpGprsQodsProfile

    • Asynchronous
      [in] NULL.
    • Synchronous
      [in] Pointer to a storage area
      [out] Pointer to a list of RILGPRSQOSPROFILE structures.

  • pdwDataSize
    [in] Pointer to the length of lpGprsQodsProfile.

    [out] Pointer to the returned data size of lpGprsQosProfile.

Return Value

Asynchronous

Positive HRESULT values indicate success and are used as command identifications for matching the asynchronous call result. Negative HRESULT values indicate an error. HRESULT error values of E_XXX are defined in winerror.h. HRESULT error values of RIL_E_XXX are defined in Ril.h.

An asynchronous result callback of RIL_RESULT_OK indicates success. The lpData notification parameter points to a RILGPRSQOSPROFILE structure.

Synchronous

HRESULT value S_OK indicates success. Information is returned in the data structure pointed to by lpGprsQodsProfile. HRESULT values of E_XXX indicate an error. Errors are defined in winerror.h.

If the return data is bigger than the input value of pdwDataSize, ERROR_INSUFFICIENT_BUFFER is returned as the synchronous function result.

Remarks

This function is asynchronous when the input value of lpGprsQodsProfile is NULL The RIL proxy translates the RIL_GetMinimumQualityOfServiceList function into IOCTL_RIL_GetMinimumQualityOfServiceList when the RIL proxy calls RIL_IOControl.

This function is synchronous when lpGprsQodsProfile is not set to NULL. The RIL driver needs to support RIL_NOTIFY_QOSMIN for the synchronous function. In the registry key HKEY_LOCAL_MACHINE\Comm\Cellular\RIL\CapsNotificationImplParams, the value RIL_CAPS_NOTIFICATION_MINIMUMQUALITYOFSERVICELIST is used to determine if RIL_NOTIFY_QOSMIN is supported. If the RIL_CAPS_NOTIFICATION_MINIMUMQUALITYOFSERVICELIST value is not set to TRUE, RIL_E_SYNCHRONOUS_DATA_UNAVAILABLE is returned. You can use RIL_GetDevCaps (hRil, RIL_CAPSTYPE_NOTIFICATIONIMPLEMENTATION) to determine which notification values are set to TRUE.
