mnt_fstype_is_netfs ()

int
mnt_fstype_is_netfs (const char *type);

mnt_fstype_is_pseudofs ()

int
mnt_fstype_is_pseudofs (const char *type);

mnt_get_fstab_path ()

const char *
mnt_get_fstab_path (void);

mnt_get_mountpoint ()

char *
mnt_get_mountpoint (const char *path);

This function finds the mountpoint that a given path resides in. path should be canonicalized. The returned pointer should be freed by the caller.

WARNING: the function compares st_dev of the path elements. This traditional way maybe be insufficient on filesystems like Linux "overlay". See also mnt_table_find_target().

mnt_get_mtab_path ()

const char *
mnt_get_mtab_path (void);

This function returns the *default* location of the mtab file. The result does not have to be writable. See also mnt_has_regular_mtab().

mnt_get_swaps_path ()

const char *
mnt_get_swaps_path (void);

mnt_has_regular_mtab ()

int
mnt_has_regular_mtab (const char **mtab,
                      int *writable);

If the file does not exist and writable argument is not NULL, then it will try to create the file.

mnt_mangle ()

char *
mnt_mangle (const char *str);

Encode str to be compatible with fstab/mtab

mnt_match_fstype ()

int
mnt_match_fstype (const char *type,
                  const char *pattern);

The pattern list of filesystems can be prefixed with a global "no" prefix to invert matching of the whole list. The "no" could also be used for individual items in the pattern list. So, "nofoo,bar" has the same meaning as "nofoo,nobar".

"bar" : "nofoo,bar" -> False (global "no" prefix)

"bar" : "foo,bar" -> True

"bar" : "foo,nobar" -> False

mnt_match_options ()

int
mnt_match_options (const char *optstr,
                   const char *pattern);

The "no" could be used for individual items in the options list. The "no" prefix does not have a global meaning.

Unlike fs type matching, nonetdev,user and nonetdev,nouser have DIFFERENT meanings; each option is matched explicitly as specified.

The "no" prefix interpretation could be disabled by the "+" prefix, for example "+noauto" matches if optstr literally contains the "noauto" string.

"xxx,yyy,zzz" : "nozzz" -> False

"xxx,yyy,zzz" : "xxx,noeee" -> True

"bar,zzz" : "nofoo" -> True

"nofoo,bar" : "+nofoo" -> True

"bar,zzz" : "+nofoo" -> False

mnt_tag_is_valid ()

int
mnt_tag_is_valid (const char *tag);

mnt_unmangle ()

char *
mnt_unmangle (const char *str);

Decode str from fstab/mtab
