<title>Description</title>
<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>

<refsect1>
<title>Return Value</title>
<para>On success, <function>sd_bus_message_read_strv()</function> returns a non-negative integer. On
