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, sizelist, count)
             Display *display;
             Window w;
             XIconSize *sizelist;
             int count;

       Status XGetIconSizes(display, w, sizelistreturn, countreturn)
             Display *display;
             Window w;
             XIconSize **sizelistreturn;
             int *countreturn;

ARGUMENTS
       display   Specifies the connection to the X server.

       count     Specifies the number of items in the size list.

       countreturn
                 Returns the number of items in the size list.

       sizelist Specifies the size list.

       sizelistreturn
                 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 manager 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 appreciated 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 supports.  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.
