GETFSENT 3 ""
C 4 NAME
getfsent, getfsspec, getfsfile, 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;
int setfsent()
void endfsent()
DESCRIPTION
Getfsent , getfsspec , 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; /* 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).
Setfsent opens the file (closing any previously opened file) or rewinds it if it is already open.
Endfsent closes the file.
Getfsspec and getfsfile 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.
