70 | ||
71 | <para><function>sd_bus_label_escape()</function> takes a | |
72 | <constant>NUL</constant>-terminated string as a argument. It will | |
73 | replace all characters which are invalid in a D-Bus object path by | |
74 | <literal>_</literal> and a hexadecimal number. As a special case, | |
75 | the empty string will be replaced by a lone <literal>_</literal>. | |
76 | <function>sd_bus_label_unescape()</function> can be used to | |
77 | reverse this process.</para> | |

81 | <title>Return Value</title> | |
82 | ||
83 | <para>On success, a new <constant>NUL</constant>-terminated string | |
84 | will be returned. It must be | |
85 | <citerefentry><refentrytitle>free</refentrytitle><manvolnum>3</manvolnum></citerefentry>d | |
86 | by the caller. If a memory allocation failure occurs, | |
87 | <constant>NULL</constant> will be returned. | |
