XAllocIconSize(3X11)	XLIB FUNCTIONS	   XAllocIconSize(3X11)

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

SYNTAX
       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 the size list.

       size_list_return
		 Returns the size list.

       w	 Specifies the window.

DESCRIPTION
       The XAllocIconSize function allocates and returns a
       pointer to a XIconSize structure.  Note that all fields in
       the XIconSize structure are initially set to zero.  If
       insufficient memory is available, XAllocIconSize returns
       NULL.  To free the memory allocated to this structure, use
       XFree.

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

       XSetIconSizes can generate BadAlloc and BadWindow errors.

       The XGetIconSizes function returns zero if a window man-
       ager has not set icon sizes; otherwise, it return nonzero.
       XGetIconSizes should be called by an application that
       wants to find out what icon sizes would be most appreci-
       ated by the window manager under which the application is

       running. The application should then use XSetWMHints 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 XFree.

       XGetIconSizes can generate a BadWindow error.

PROPERTIES
       WM_ICON_SIZES
		 The window manager may set this property on the
		 root window to specify the icon sizes it sup-
		 ports. The C type of this property is
		 XIconSize.

STRUCTURES
       The XIconSize 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
       BadAlloc The server failed to allocate the requested
		 resource or server memory.

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