Name
       XGetVisualInfo, XMatchVisualInfo, XVisualIDFromVisual, XVisualInfo - obtain visual information and visual structure

Syntax
       XVisualInfo *XGetVisualInfo(display, vinfo_mask, vinfo_template, nitems_return)
	  Display *display;
	  long vinfo_mask;
	  XVisualInfo *vinfo_template;
	  int *nitems_return;

       Status XMatchVisualInfo(display, screen, depth, class, vinfo_return)
	  Display *display;
	  int screen;
	  int depth;
	  int class;
	  XVisualInfo *vinfo_return;

       VisualID XVisualIDFromVisual(visual)
	   Visual *visual;

Arguments
       class	 Specifies the class of the screen.

       depth	 Specifies the depth of the screen.

       display	 Specifies the connection to the X server.

       nitems_return
		 Returns the number of matching visual structures.

       screen	 Specifies the screen.

       visual	 Specifies the visual type.

       vinfo_mask
		 Specifies the visual mask value.

       vinfo_return
		 Returns the matched visual information.

       vinfo_template
		 Specifies the visual attributes that are to be used in matching the visual structures.

Description
       The function returns a list of visual structures that match the attributes specified by vinfo_template.	If no visual structures match the
       template using the specified vinfo_mask, returns a NULL.  To free the data returned by this function, use

       The function returns the visual information for a visual that matches the specified depth and class for a screen.  Because multiple visuals
       that match the specified depth and class can exist, the exact visual chosen is undefined.  If a visual is found, returns nonzero and the
       information on the visual to vinfo_return.  Otherwise, when a visual is not found, returns zero.

       The function returns the visual ID for the specified visual type.

Structures
       The structure contains:

       /* Visual information mask bits */

       #define				     0x1
