|
filesystem name |
Returns : |
1 for filesystems like cifs, nfs, ... or 0. |
int mnt_fstype_is_pseudofs (const char *type
);
|
filesystem name |
Returns : |
1 for filesystems like proc, sysfs, ... or 0. |
const char * mnt_get_fstab_path (void
);
Returns : |
path to /etc/fstab or $LIBMOUNT_FSTAB. |
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.
|
pathname |
Returns : |
allocated string with the target of the mounted device or NULL on error |
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()
.
Returns : |
path to /etc/mtab or $LIBMOUNT_MTAB. |
const char * mnt_get_swaps_path (void
);
Returns : |
path to /proc/swaps or $LIBMOUNT_SWAPS. |
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.
|
returns path to mtab |
|
returns 1 if the file is writable |
Returns : |
1 if /etc/mtab is a regular file, and 0 in case of error (check errno for more details). |
char * mnt_mangle (const char *str
);
Encode str
to be compatible with fstab/mtab
|
string |
Returns : |
newly allocated string or NULL in case of error. |
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
|
filesystem type |
|
filesystem name or comma delimited list of names |
Returns : |
1 if type is matching, else 0. This function also returns
0 if pattern is NULL and type is non-NULL. |
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
|
options string |
|
comma delimited list of options |
Returns : |
1 if pattern is matching, else 0. This function also returns 0
if pattern is NULL and optstr is non-NULL. |
int mnt_tag_is_valid (const char *tag
);
|
NAME=value string |
Returns : |
1 if the tag is parsable and tag NAME= is supported by libmount, or 0. |
