参与错误注入

若要参与错误信息检索，PSHED 插件必须实现以下回调函数：

GetInjectionCapabilities

InjectError

下面的代码示例演示如何实现这些回调函数。

//
// The PSHED plug-in's GetInjectionCapabilities callback function
//
NTSTATUS
  GetInjectionCapabilities(
    IN OUT PVOID PluginContext,
    OUT PWHEA_ERROR_INJECTION_CAPABILITIES Capabilities
    )
{
  // Set the members in the structure pointed to by the
  // Capabilities parameter to indicate the error injection
  // capabilities supported by the PSHED plug-in.
  ...

  // Return success status
  return STATUS_SUCCESS;
}

//
// The PSHED plug-in's InjectError callback function
//
NTSTATUS
  InjectError(
    IN OUT PVOID PluginContext,
    IN ULONG ErrorType,
 IN ULONGLONG Parameter1,
    IN ULONGLONG Parameter2,
    IN ULONGLONG Parameter3,
    IN ULONGLONG Parameter4
    )
{
  // Inject the hardware error specified in the ErrorType
  // parameter into the hardware platform.
  // Parameter1 through Parameter4 contain any additional
  // data that is required to inject the error.
  ...

  // Note: For injected errors that are fatal or otherwise
  // unrecoverable, this callback function might not continue
  // execution past this point before the Windows kernel
  // generates a bug check in response to the error condition.

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

  // Failed to update the error record
  else
  {
    return STATUS_UNSUCCESSFUL;
  }
}

参与错误注入的 PSHED 插件在向操作系统注册自身时必须指定 PshedFAErrorInjection 标志。
