- * Name: nxtk_setposition
- *
- * Description:
- * Set the position for the selected client window. This position does not
- * include the offsets for the borders nor for any toolbar. Those offsets
- * will be added in to set the full window position.
- *
- * Input Parameters:
- * hfwnd - The window handle returned by nxtk_openwindow
- * pos - The new position of the client sub-window
- *
- * Return:
- * OK on success; ERROR on failure with errno set appropriately
