GETFSENT(3)						   BSD Library Functions Manual 					       GETFSENT(3)

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;    /* File system type, ufs, nfs */
		   char    *fs_mntops;	   /* Mount options ala -o */
		   char    *fs_type;	   /* FSTAB_* from fs_mntops */
		   int	   fs_freq;	   /* dump frequency, in days */
		   int	   fs_passno;	   /* pass number on parallel fsck */
	   };

     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 on EOF or error.  The setfsent() function returns 0 on failure,
     1 on success.  The endfsent() function returns nothing.

FILES

     /etc/fstab

HISTORY

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

BUGS

     The data space used by these functions is thread-specific; if future use requires the data, it should be copied before any subsequent calls
     to these functions overwrite it.
