gchar *
udisks_decode_udev_string (const gchar *str
);
Unescapes sequences like \x20 to " " and ensures the returned string is valid UTF-8.
If the string is not valid UTF-8, try as hard as possible to convert to UTF-8.
If NULL
is passed, then NULL
is returned.
See udev_util_encode_string()
in libudev/libudev-util.c in the udev
tree for what kinds of strings can be used.
void udisks_safe_append_to_object_path (GString *str
,const gchar *s
);
Appends s
to str
in a way such that only characters that can be
used in a D-Bus object path will be used. E.g. a character not in
A-Z[0-9]_
will be escaped as _HEX where
HEX is a two-digit hexadecimal number.
Note that his mapping is not bijective - e.g. you cannot go back to the original string.
guint64 udisks_daemon_util_block_get_size (GUdevDevice *device
,gboolean *out_media_available
,gboolean *out_media_change_detected
);
Gets the size of the device
top-level block device, checking for media in the process
device |
A GUdevDevice for a top-level block device. |
|
out_media_available |
Return location for whether media is available or |
[out] |
out_media_change_detected |
Return location for whether media change is detected or |
[out] |
gchar * udisks_daemon_util_resolve_link (const gchar *path
,const gchar *name
);
Resolves the symlink path
/name
.
gchar ** udisks_daemon_util_resolve_links (const gchar *path
,const gchar *dir_name
);
Resolves all symlinks in path
/dir_name
. This can be used to
easily walk e.g. holders or slaves of block devices.
gboolean udisks_daemon_util_check_authorization_sync (UDisksDaemon *daemon
,UDisksObject *object
,const gchar *action_id
,GVariant *options
,const gchar *message
,GDBusMethodInvocation *invocation
);
Checks if the caller represented by invocation
is authorized for
the action identified by action_id
, optionally displaying message
if authentication is needed. Additionally, if the caller is not
authorized, the appropriate error is already returned to the caller
via invocation
.
The calling thread is blocked for the duration of the authorization
check which could be a very long time since it may involve
presenting an authentication dialog and having a human user use
it. If “auth.no_user_interaction” in options
is TRUE
no authentication dialog will be presented and the check is not
expected to take a long time.
See Table 1, “Known polkit variables” for the variables that
can be used in message
but note that not all variables can be used
in all checks. For example, any check involving a UDisksDrive or a
UDisksBlock object can safely include the fragment
the drive, e.g. “INTEL SSDSA2MH080G1GC (/dev/sda1)” or the block device file e.g. “/dev/vg_lucifer/lv_root” or “/dev/sda1”. However this won't work for operations that isn't on a drive or block device, for example calls on the
Managerobject.
