Format  Sint32 CDC_CdSeek (CdcPos * pos)
 Input  pos: Position parameter
 Output  None
 Function value  Returns an error code.
 Function  Moves (seeks) the playback position (pickup) according to the specified position parameter. 

 Note: If you use the stop command at the end of CD playback, it will be slower when accessing the CD again.
. As long as you continue to access the CD, you should normally use the pause command. 

 Example   (1) Frame address specification 
  Sint32 ret;
:  CdcPos poswk, * pos = & poswk; / * Position parameter variable definition * /
  CDC_POS_PTYPE (pos) = CDC_PTYPE_FAD;
  CDC_POS_FAD (pos) = fad; / * Frame address * /
  ret = CDC_CdSeek (pos); / * Start of seek * / 

   (2) Track / index specification 
  CdcPos poswk, * pos = & poswk;
  CDC_POS_PTYPE (pos) = CDC_PTYPE_TNO;
  CDC_POS_TNO (pos) = tno; / * Track number * /
  CDC_POS_IDX (pos) = x; / * Index number * /
  ret = CDC_CdSeek (pos); 

   (3) Stop CD playback (specify the default value: seek to the home position) ... Stop 
  CdcPos poswk, * pos = & poswk;
  CDC_POS_PTYPE (pos) = CDC_PTYPE_DFL;
  ret = CDC_CdSeek (pos); 

   (4) Pause CD playback (unchanged designation: seek to current position) ... Pause 
  CdcPos poswk, * pos = & poswk;
  CDC_POS_PTYPE (pos) = CDC_PTYPE_NOCHG;
  ret = CDC_CdSeek (pos);
