View Ref-File7.10.31  Bindings for v_opnwk                                      TOS

 C:          void v_opnwk ( int16_t *work_in, int16_t *handle, int16_t 
             *work_out );

 Binding:

             void v_opnwk (int16_t *work_in, int16_t *handle,
                           int16_t *work_out)
             {
                intin[0..15] = work_in[0..15];
 
                contrl[0] = 1;
                contrl[1] = 0;
                contrl[3] = 16;
                contrl[6] = 0;
 
                vdi ();
 
                *handle = contrl[6];
                work_out[0..44]  = intout[0..44];
                work_out[45..56] = ptsout[0..11];
             }

             Note: The specified binding is valid for use under NVDI. 
             With printer drivers some special features have to be 
             taken into account: First of all, with matrix printers 
             the maximum resolution can be specified, as follows:

              ptsin[0] =   Maximum resolution in X-direction
              ptsin[1] =   Maximum resolution in Y-direction
              contrl[1] =  1

             In addition, the address of the internal buffer for the 
             Atari SLM laser page-printers can be obtained:

              contrl[0] = High word, and
              contrl[1] = Low word of the buffer address
