PipeWire Client
|
|
...............
|
|
|
|
Lua objects that bind a :ref:`WpClient <client_api>`
|
|
contain the following methods:
|
|
|
|
.. function:: Client.update_permissions(self, perms)
|
|
|
|
Binds :c:func:`wp_client_update_permissions`
|
|
|
|
Takes a table where the keys are object identifiers and the values are
|
|
permission strings.
|
|
|
|
Valid object identifiers are:
|
|
|
|
- A number, meaning the bound ID of a proxy
|
|
- The string "any" or the string "all", which sets the default permissions
|
|
for this client
|
|
|
|
The permission strings have a chmod-like syntax (ex. "rwx" or "r-xm"), where:
|
|
|
|
- "r" means permission to read the object
|
|
- "w" means permission to write data to the object
|
|
- "x" means permission to call methods on the object
|
|
- "m" means permission to set metadata for the object
|
|
- "-" is ignored and can be used to make the string more readable when
|
|
a permission flag is omitted
|
|
|
|
**Example:**
|
|
|
|
.. code-block:: lua
|
|
|
|
client:update_permissions {
|
|
["all"] = "r-x",
|
|
[35] = "rwxm",
|
|
}
|
|
|
|
:param self: the proxy
|
|
:param table perms: the permissions to update for this client
