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.

typedef struct {
int min_width, min_height;

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