GETFSENT(3) MachTen Programmer’s Manual GETFSENT(3)

NAME
getfsent, getfsspec, getfsfile, setfsent, endfsent - get file system de-
scriptor file entry

SYNOPSIS
#include <fstab.h>

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 ig-
nored.

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.
