參與錯誤來源控制

若要參與錯誤原始檔控制，PSHED 外掛程式必須實作下列回呼函式：

SetErrorSourceInfo

啟用錯誤來源

停用錯誤來源

下列程式代碼範例示範如何實作這些回呼函式。

//
// The PSHED plug-in's SetErrorSourceInfo callback function
//
NTSTATUS
  SetErrorSourceInfo(
    IN OUT PVOID PluginContext,
    IN PWHEA_ERROR_SOURCE_DESCRIPTOR ErrorSource
    )
{
  // Check if the plug-in supports configuring
  // the specified error source.
  if (...)
  {
    // Save the new configuration data for the error
    // source in nonvolatile storage and apply the
    // configuration changes to the error source such
    // that they will become effective after the
    // system is restarted.
    ...

    // If successful, return success status
    if (...)
    {
      return STATUS_SUCCESS;
    }

    // Failed to configure the error source
    else
    {
      return STATUS_UNSUCCESSFUL;
    }
  }

  // Not supported by the plug-in
  else
  {
    return STATUS_NOT_SUPPORTED;
  }
}

//
// The PSHED plug-in's EnableErrorSource callback function
//
NTSTATUS
  EnableErrorSource(
    IN OUT PVOID PluginContext,
    IN PWHEA_ERROR_SOURCE_DESCRIPTOR ErrorSource
    )
{
  // Check if the plug-in supports enabling
  // the specified error source.
  if (...)
  {
    // Enable the error source
    ...

    // If successful
    if (...)
    {
      // Return success status
      return STATUS_SUCCESS;
    }

    // Failed to enable the error source
    else
    {
      return STATUS_UNSUCCESSFUL;
    }
  }

  // Not supported by the plug-in
  else
  {
    return STATUS_NOT_SUPPORTED;
  }
}

//
// The PSHED plug-in's DisableErrorSource callback function
//
NTSTATUS
  DisableErrorSource(
    IN OUT PVOID PluginContext,
    IN PWHEA_ERROR_SOURCE_DESCRIPTOR ErrorSource
    )
{
  // Check if the plug-in supports disabling
  // the specified error source.
  if (...)
  {
    // Disable the error source
    ...

    // If successful
    if (...)
    {
      // Return success status
      return STATUS_SUCCESS;
    }

    // Failed to disable the error source
    else
    {
      return STATUS_UNSUCCESSFUL;
    }
  }

  // Not supported by the plug-in
  else
  {
    return STATUS_NOT_SUPPORTED;
  }
}

參與錯誤原始檔控制的 PSHED 外掛程式，必須在 向作系統註冊 本身時，指定 PshedFAErrorSourceControl 旗標。
