Function Documentation

Bool NVCTRLQueryDDCCICapabilities (  Display *  dpy,
int  screen,
unsigned int  display_mask,
unsigned int **  nvctrl_vcp_supported,
unsigned int **  possible_values_offset,
unsigned int **  possible_values_size,
unsigned int **  nvctrl_vcp_possible_values,
unsigned int **  nvctrl_string_vcp_supported
) 
 

Bool XNVCTRLIsNvScreen (  Display *  dpy,
int  screen
) 
 

Bool XNVCTRLQueryAttribute (  Display *  dpy,
int  screen,
unsigned int  display_mask,
unsigned int  attribute,
int *  value
) 
 

Returns True if the attribute exists. Returns False otherwise. If XNVCTRLQueryAttribute returns True, value will contain the value of the specified attribute.

Not all attributes require the display_mask parameter; see NVCtrl.h for details.

Calling this function is equivalent to calling XNVCTRLQueryTargetAttribute() with the target_type set to NV_CTRL_TARGET_TYPE_X_SCREEN and target_id set to 'screen'.

Possible errors: BadValue - The screen doesn't exist. BadMatch - The NVIDIA driver is not present on that screen.

Bool XNVCTRLQueryExtension (  Display *  dpy,

Returns True if the extension exists, returns False otherwise. event_basep and error_basep are the extension event and error bases. Currently, no extension specific errors or events are defined.
