/**********************************************************************

****/

* Attribute Targets

* Targets define attribute groups. For example, some attributes are

only

* valid to set on a GPU, others are only valid when talking about an

* X Screen. Target types are then what is used to identify the target

* group of the attribute you wish to set/query.

* Here are the supported target types:

#define NV_CTRL_TARGET_TYPE_X_SCREEN 0

#define NV_CTRL_TARGET_TYPE_GPU 1

#define NV_CTRL_TARGET_TYPE_FRAMELOCK 2

#define NV_CTRL_TARGET_TYPE_VCSC 3 /* Visual Computing System */

#define NV_CTRL_TARGET_TYPE_GVI 4

/**********************************************************************

****/

* Attributes

* Some attributes may only be read; some may require a display_mask

* argument and others may be valid only for specific target types.

* This information is encoded in the "permission" comment after each

* attribute #define, and can be queried at run time with

* XNVCTRLQueryValidAttributeValues() and/or

* XNVCTRLQueryValidTargetAttributeValues()
