fstab(4)

NAME

fstab − static information about the file systems

SYNOPSIS

#include <fstab.h>

REMARKS

This file is provided only for portability of applications developed under BSD. New applications should use <mntent.h> and getmntent() (see getmntent(3)).

DESCRIPTION

Including <fstab.h> provides portability for BSD applications using getfsent() (see getfsent(3X)). getfsent() reads file /etc/checklist and fills in the fstab structure defined in <fstab.h>. Note that, in BSD systems, /etc/fstab is read using the getfsent(3X) routines. On HP-UX systems, getfsent(3X) emulates the BSD behavior. Note also that including and using <checklist.h> does not produce the same behavior from getfsent(3X) as including and using <fstab.h>.

The struct fstab structure is declared in <fstab.h>, and includes the following members:

char    *fs_spec    Block special device name
char    *fs_file    File system path prefix
char    *fs_type    Type of file system (FSTAB_*)
int     fs_passno   Pass number on parallel dump
int     fs_freq     Dump frequency, in days

BSD applications that depend on the position of elements within the structure are not portable.
