+
+    <para><function>sd_bus_message_read_strv()</function> gives access to an array of strings in message
+    <parameter>m</parameter>. The "read pointer" in the message must be right before an array of strings. On
+    success, A pointer to the <constant>NULL</constant>-terminated array of strings is returned in the output
+    parameter <parameter>l</parameter>. Note that ownership of this array is transferred to the caller.
+    Hence, the caller is responsible for freeing this array and its contents.</para>

+    <title>Return Value</title>
+
+    <para>On success, <function>sd_bus_message_read_strv()</function> returns a non-negative integer. On
