<title>Description</title>
<para><function>sd_bus_interface_name_is_valid()</function> checks if a given string
<parameter>p</parameter> is a syntactically valid bus interface name. Similarly,
<function>sd_bus_service_name_is_valid()</function> checks if the argument is a valid bus service name,
<function>sd_bus_member_name_is_valid()</function> checks if the argument is a valid bus interface member
name, and <function>sd_bus_object_path_is_valid()</function> checks if the argument is a valid bus object
path. Those functions generally check that only allowed characters are used and that the length of the
string is within limits.</para>
</refsect1>
<refsect1>
<title>Return Value</title>
<para>Those functions return 1 if the argument is a valid interface / service / member name or object
path, and 0 if it is not. If the argument is NULL, an error is returned.</para>
<refsect2>
<title>Errors</title>
<para>Returned errors may indicate the following problems:</para>
<variablelist>
<varlistentry>
<term><constant>-EINVAL</constant></term>
<listitem><para>The <parameter>p</parameter> parameter is
<constant>NULL</constant>.</para></listitem>
