9.6.2 Low-Level Table Access Routines

The following 2 routines provide low-level access to the data in ASCII or binary tables and are mainly useful as an efficient way to copy all or part of a table from one location to another. These routines simply read or write the specified number of consecutive bytes in an ASCII or binary table, without regard for column boundaries or the row length in the table. These routines do not perform any machine dependent data conversion or byte swapping. See Appendix B for the definition of the parameters used in these routines.

Read or write a consecutive array of bytes from an ASCII or binary table

  int fits_read_tblbytes / ffgtbb
      (fitsfile *fptr, LONGLONG firstrow, LONGLONG firstchar, LONGLONG nchars,
       > unsigned char *values, int *status)

  int fits_write_tblbytes / ffptbb
      (fitsfile *fptr, LONGLONG firstrow, LONGLONG firstchar, LONGLONG nchars,
       unsigned char *values, > int *status)
