typedef void (*PK_FFSEEK_f_t)(const int *guise, const int *strid,
                              const int *pos,
                                    int *ifail);



  Reset file pointer. This function is documented for legacy
  purposes only, and should not be implemented for new Parasolid applications.


Receives:
  int                      *guise          --- class of file: FFCROL
  int                      *strid          --- frustrum strid
  int                      *pos            --- pointer into file stream

Returns:
  int                      *ifail          --- error code: FR_no_errors


Description:
  This function resets the file pointer within a rollback file to a value
  noted earlier by FFTELL. Subsequent reading or writing starts from
  this position. Note that the file pointer cannot be set for non-rollback
  files (i.e. those which were opened by FFOPRD or FFOPWR)
