<title>Description</title>
|
||
|
||
<para><function>sd_bus_label_escape()</function> takes a
|
||
<constant>NUL</constant>-terminated string as a argument. It will
|
||
replace all characters which are invalid in a D-Bus object path by
|
||
<literal>_</literal> and a hexadecimal number. As a special case,
|
||
the empty string will be replaced by a lone <literal>_</literal>.
|
||
<function>sd_bus_label_unescape()</function> can be used to
|
||
reverse this process.</para>
