KCMS Calibrator Tool Loadable Interface Guide

`KCMSCVisuals`

typedef struct _KCMSCVisuals {
    Display * display;
    int       screen;
    int      	numVisuals;			/* dynamic array size */
    XVisualInfo ** visuals;		/* visuals to get data for */

    
} KCMSCVisuals;

KCMSCVisuals is a structure that identifies to the loadable module the display and visuals upon which to perform measurements. The members in this structure are described below:

`display`	Is a `Display` pointer. The `Display` pointer is for use when the loadable module makes an X library call (such as `XCreateWindow()`) to connect to the local windowing system. (For details on `Display`, see the XLib Programming Manual.)
`screen`	Is the screen number to be used in Xll calls. Calibrator Tool fills in the value of this field.
`numVisuals`	Is the number of X visuals for which color measurement data is needed. Calibrator Tool fills in the value of this field based on the number of X visuals to be updated. (For details, see "Slow and Fast Mode Measurements" in Chapter 4, Measuring Monitor Response.)
`visuals`	Is an array of `XVisualInfo` pointers. (See "`XVisualInfo`" below for the format of this structure.)

`XVisualInfo`

The XVisualInfo structure has the format shown below. For details on the members of this structure, see the XLib Programming Manual.

typedef struct {
 	Visual* visual;
 	VisualID visualid;
 	int screen_num;
 	unsigned int depth;
 	int class;
 	unsigned long red_mask;
 	unsigned long green_mask;
		unsigned long blue_mask;
 	int colormap_size; /* Same as map_entries member of Visual */
 	int bits_per_rgb;
 } XVisualInfo;
