DESCRIPTION: Used in conjunction with OUTPUT_TO_CALLBACK, this is a simple callback function the user may use to obtain the feedback stream. The function will be called once per fully qualified feedback stream entry.

Parameters:

	categoryId	Contains the bit from the NVAPI_OGLEXPERT_REPORT mask that corresponds to the current message
	messageId	Unique ID for the current message
	detailLevel	Contains the bit from the NVAPI_OGLEXPERT_DETAIL mask that corresponds to the current message
	objectId	Unique ID of the object that corresponds to the current message
	messageStr	Text string from the current message

This function configures OpenGL Expert Mode global defaults. These settings apply to any OpenGL application which starts up after these values are applied (i.e. these settings *do not* apply to currently running applications).

SUPPORTED OS: Windows XP and higher

Since:

Version: 84.11 (Rel80) / 88.00 (Rel85)

Parameters:

	expertDetailLevel	Value which specifies the detail level in the feedback stream. This is a mask made up of NVAPI_OGLEXPERT_LEVEL bits.
	expertReportMask	Mask made up of NVAPI_OGLEXPERT_REPORT bits, this parameter specifies the areas of functional interest.
	expertOutputMask	Mask made up of NVAPI_OGLEXPERT_OUTPUT bits, this parameter specifies the feedback output location. Note that using OUTPUT_TO_CALLBACK here is meaningless and has no effect, but using it will not cause an error.

Returns:

NVAPI_ERROR or NVAPI_OK

	expertReportMask	Mask made up of NVAPI_OGLEXPERT_REPORT bits, this parameter specifies the areas of functional interest.

Returns:

NVAPI_ERROR or NVAPI_OK

This function configures OpenGL Expert Mode, an API usage feedback and advice reporting mechanism. The effects of this call are applied only to the current context, and are reset to the defaults when the context is destroyed.

This feature is valid at runtime only when GLExpert functionality has been built into the OpenGL driver installed on the system. All Windows Vista OpenGL drivers provided by NVIDIA have this instrumentation included by default. Windows XP, however, requires a special display driver available with the NVIDIA PerfSDK found at developer.nvidia.com.

These functions are valid only for the current OpenGL context. Calling these functions prior to creating a context and calling MakeCurrent with it will result in errors and undefined behavior.

SUPPORTED OS: Windows XP and higher

Since:

Version: 84.11 (Rel80) / 88.00 (Rel85)

Parameters:

	expertDetailMask	Mask made up of NVAPI_OGLEXPERT_DETAIL bits, this parameter specifies the detail level in the feedback stream.
	expertReportMask	Mask made up of NVAPI_OGLEXPERT_REPORT bits, this parameter specifies the areas of functional interest.
	expertOutputMask	Mask made up of NVAPI_OGLEXPERT_OUTPUT bits, this parameter specifies the feedback output location.
	expertCallback	Used in conjunction with OUTPUT_TO_CALLBACK, this is a simple callback function the user may use to obtain the feedback stream. The function will be called once per fully qualified feedback stream extry.

Return values:

	NVAPI_API_NOT_INTIALIZED	NVAPI not initialized
	NVAPI_NVIDIA_DEVICE_NOT_FOUND	No NVIDIA GPU found
	NVAPI_OPENGL_CONTEXT_NOT_CURRENT	No NVIDIA OpenGL context which supports GLExpert has been made current
	NVAPI_ERROR	OpenGL driver failed to load properly
	NVAPI_OK	Success
