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_mtab_path ()

const char *        mnt_get_mtab_path                   (void);

This function returns *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 filesystem 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 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 disable by "+" prefix, for example "+noauto" matches if optstr literally contains "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_unmangle ()

char *              mnt_unmangle                        (const char *str);

Decode str from fstab/mtab
