<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>

<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 <constant>NULL</constant>, an error is returned.</para>
