Name
       XAllocIconSize, XSetIconSizes, XGetIconSizes, XIconSize - allocate icon size structure and set or read a window's WM_ICON_SIZES property

       XIconSize *XAllocIconSize()

       XSetIconSizes(display, w, size_list, count)
	  Display *display;
	  Window w;
	  XIconSize *size_list;
	  int count;

       Status XGetIconSizes(display, w, size_list_return, count_return)
	  Display *display;
	  Window w;
	  XIconSize **size_list_return;
	  int *count_return;

Arguments
       display	 Specifies the connection to the X server.

       count	 Specifies the number of items in the size list.

       count_return
		 Returns the number of items in the size list.

       size_list Specifies a pointer to the size list.

       size_list_return
		 Returns a pointer to the size list.

       w	 Specifies the window.

Description
       The function allocates and returns a pointer to a structure.  Note that all fields in the structure are initially set to zero.  If insuffi-
       cient memory is available, returns NULL.  To free the memory allocated to this structure, use

       The function is used only by window managers to set the supported icon sizes.

       can generate and errors.

       The function returns zero if a window manager has not set icon sizes or nonzero otherwise.  should be called by an application that wants
       to find out what icon sizes would be most appreciated by the window manager under which the application is running.  The application should
       then use to supply the window manager with an icon pixmap or window in one of the supported sizes.  To free the data allocated in
       size_list_return, use

       can generate a error.

Properties
       WM_ICON_SIZES
		 The window manager may set this property on the root window to specify the icon sizes it supports.  The C type of this property
		 is

Structures
       The structure contains:

       typedef struct {
	    int min_width, min_height;
	    int max_width, max_height;
	    int width_inc, height_inc;
       } XIconSize;

       The width_inc and height_inc members define an arithmetic progression of sizes (minimum to maximum) that represent the supported icon
       sizes.

Diagnostics
       The server failed to allocate the requested resource or server memory.

       A value for a Window argument does not name a defined Window.
