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>

<div>Hi,</div>
<div><br>
</div>
in some function that return a value with PV_VAL_PKG or
PV_VAL_SHM, the allocated memory is supposed to be freed
by core ?
<div><br>
</div>
<div>
<div>script example</div>
<div><br>
</div>
<div>my_function("some param","$var(result)");</div>
<div><span style="font-size:10pt"><br>
</span></div>
<div><span style="font-size:10pt">in code => </span></div>
<div>dst_val->flags = PV_VAL_STR | PV_VAL_PKG;</div>
<div><span style="font-size:10pt">dst_pv->setf(msg,
&dst_pv->pvp, (int)EQ_T, &dst_val);</span></div>
<div><br>
</div>
<div>when $var(result) is freed, will it free the
allocated string ?</div>
<div><br>
</div>
<div><br>
</div>
<div>if( $(myPvar{my.mytransform,transformParameter})
== $null) {</div>
<div> $var(x) = <span style="font-size:10pt">$(myPvar{my.mytransform,transformParameter});</span></div>
<div>}</div>
<div>
<div><span style="font-size:10pt"><br>
</span></div>
<div><span style="font-size:10pt">in code => </span></div>
<div>dst_val->flags = PV_VAL_STR | PV_VAL_PKG;</div>
<div><br>
</div>
</div>
<div>will the memory allocated <span
style="font-size:10pt">be freed</span><span
style="font-size:10pt"> in the comparison line ?</span></div>
<div><span style="font-size:10pt">will</span><span

style="font-size:10pt">the memory allocated </span><span
