DDEESSCCRRIIPPTTIIOONN
     The ggeettffsseenntt(), ggeettffssssppeecc(), and ggeettffssffiillee() functions each return a
     pointer to an object with the following structure containing the broken-
     out fields of a line in the file system description file, <_f_s_t_a_b_._h>.

           struct fstab {
                   char    *fs_spec;       /* block special device name */
                   char    *fs_file;       /* file system path prefix */
                   char    *fs_vfstype;    /* type of file system */
                   char    *fs_mntops;     /* comma separated mount options */
                   char    *fs_type;       /* rw, ro, sw, or xx */
                   int     fs_freq;        /* dump frequency, in days */
                   int     fs_passno;      /* pass number on parallel dump */
           };

     The fields have meanings described in fstab(5).

     The sseettffsseenntt() function opens the file (closing any previously opened
     file) or rewinds it if it is already open.

     The eennddffsseenntt() function closes the file.

     The ggeettffssssppeecc() and ggeettffssffiillee() functions search the entire file (opening
     it if necessary) for a matching special file name or file system file
     name.

     For programs wishing to read the entire database, ggeettffsseenntt() reads the
     next entry (opening the file if necessary).

     All entries in the file with a type field equivalent to FSTAB_XX are ig-
     nored.

RREETTUURRNN VVAALLUUEESS
     The ggeettffsseenntt(), ggeettffssssppeecc(), and ggeettffssffiillee() functions return a null
     pointer (0) on EOF or error.  The sseettffsseenntt() function returns 0 on fail-
     ure, 1 on success.  The eennddffsseenntt() function returns nothing.

HHIISSTTOORRYY
     The ggeettffsseenntt() function appeared in 4.0BSD; the eennddffsseenntt(), ggeettffssffiillee(),
     ggeettffssssppeecc(), and sseettffsseenntt() functions appeared in 4.3BSD.

BBUUGGSS
     These functions use static data storage; if the data is needed for future
     use, it should be copied before any subsequent calls overwrite it.
