    Hello,<br>
    <br>
    if you assign to a $var(...), it makes a deep copy in pkg memory. It
    is up to you to handle further the content of dst_val and free it
    properly.<br>
    <br>
    If you set the PV_VAL_PKG (value must be in a pkg_malloc() pointer)
    or PV_VAL_SHM (value must be in a shm_malloc() pointer) for dst_val,
    then you can call pv_value_destroy() to get it freed. But it is not
    necessary, if you free it in the code yourself.<br>
    <br>
    Cheers,<br>
    Daniel<br>
