NAME

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

SYNOPSIS

       #include <fstab.h>

       struct fstab *getfsent()

       struct fstab *getfsspec(spec)
       char *spec;

       struct fstab *getfsfile(file)
       char *file;

       struct fstab *getfstype(type)
       char *type;

       int setfsent()

       int endfsent()

DESCRIPTION

       Getfsent,  getfsspec,  getfstype,  and  getfsfile 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, <fstab.h>.

	      struct fstab {
		   char *fs_spec;
		   char *fs_file;
		   char *fs_type;
		   int	fs_freq;
		   int	fs_passno;
	      };

       The fields have meanings described in fstab(5).

       Getfsent reads the next line of the file, opening the file if necessary.

       Setfsent opens and rewinds the file.

       Endfsent closes the file.

       Getfsspec and getfsfile sequentially search from the beginning of the file until a matching special file name or file system file  name	is
       found, or until EOF is encountered.  Getfstype does likewise, matching on the file system type field.

FILES

DIAGNOSTICS

       Null pointer (0) returned on EOF or error.

BUGS

       All information is contained in a static area so it must be copied if it is to be saved.

NAME

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

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #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

     The getfsent(), getfsspec(), and getfsfile() 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, <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

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

FILES

     /etc/fstab

SEE ALSO

HISTORY

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

BUGS

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