PFN_IDDCXGETVERSION callback function

Description

PFN_IDDCXGETVERSION is a pointer to an OS callback function that gets the IddCx (Indirect Display Driver Class eXtension) version.

Parameters

DriverGlobals [in]

Pointer to an IDD_DRIVER_GLOBALS structure containing system-defined per-driver data.

pOutArgs [out]

Pointer to an IDARG_OUT_GETVERSION structure in which the driver will return the current IddCx version.

Return value

(NTSTATUS) PFN_IDDCXGETVERSION returns STATUS_SUCCESS if the operation succeeds. Otherwise, it returns an appropriate NTSTATUS error code.

Remarks

An indirect display driver (IDD) should not use this pointer to directly call the function that it points to. IDDs should instead call IddCxGetVersion.
