GETFSENT(3)

Contents


NAME    [Toc]    [Back]

     getfsent, getfsspec, getfsfile, setfsent, endfsent - get file system
     descriptor file entry

LIBRARY    [Toc]    [Back]

     Standard C Library (libc, -lc)

SYNOPSIS    [Toc]    [Back]

     #include <fstab.h>

     struct fstab *
     getfsent(void);

     struct fstab *
     getfsspec(const char *spec);

     struct fstab *
     getfsfile(const char *file);

     int
     setfsent(void);

     void
     endfsent(void);

DESCRIPTION    [Toc]    [Back]

     The getfsent(), getfsspec(), and getfsfile() functions each return a
     pointer to an object with the following structure containing the brokenout
 fields of a line in the file system description file, <fstab.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 setfsent() function opens the file (closing any previously opened
     file) or rewinds it if it is already open.

     The endfsent() function closes the file.

     The getfsspec() and getfsfile() 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, getfsent() reads the
     next entry (opening the file if necessary).

     All entries in the file with a type field equivalent to FSTAB_XX are
     ignored.

RETURN VALUES    [Toc]    [Back]

     The getfsent(), getfsspec(), and getfsfile() functions return a null
     pointer (0) on EOF or error.  The setfsent() function returns 0 on failure,
 1 on success.  The endfsent() function returns nothing.

FILES    [Toc]    [Back]

     /etc/fstab

HISTORY    [Toc]    [Back]

     The getfsent() function appeared in 4.0BSD; the endfsent(), getfsfile(),
     getfsspec(), and setfsent() functions appeared in 4.3BSD.

BUGS    [Toc]    [Back]

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