 Name:         »Show cursor« - Switch on graphic cursor.

 Opcode:       122

 Syntax:       void v_show_c ( int16_t handle, int16_t reset );

 Description:  The call v_show_c 'unhides' the graphic cursor, or 
               cancels the call of the v_hide_c function. The 
               following apply:

                Parameter  Meaning

                handle     Workstation identifier
                reset      Flag:
                            0 =    Ignore number of Hide cursor calls
                            <>0 =  Normal Show cursor functionality 
                                   (cursor is only displayed if the 
                                   function has been called the same 
                                   number of times as v_hide_c)

               In GEM programs, it is imperative that the AES function 
               graf_mouse is used to switch the mouse cursor on and 
               off.

               Note: The input functions of the VDI work only on the 
               physical workstation, which is normally used by the 
               AES. Therefore it is better to fall back to using 
               graf_mouse instead.

 Return value: The function does not return a result.

 Availability: Supported by all screen drivers.

 Group:        Input functions
