Windows Driver Kit DDI reference (ns-iddcx-idarg_in_reportcriticalerror)

Description

The IDARG_IN_REPORTCRITICALERROR structure contains information about a critical error being reported by an indirect display driver (IDD).

Members

`MajorErrorCode`

[In] The major error code for this critical error. Valid range 0-0xff inclusive. IddCx will add 0x100 to this value before passing to Windows Error Reporting when creating a memory dump.

`MinorErrorCode`

[in] The minor error code for this critical error. Valid range 0-0xff inclusive.

Remarks

It is recommended that the driver use a unique combination of a major code and minor code so these cases can be identified in crashes and Watson reports.
