Hi,
if we return val.flags = PV_VAL_NULL, does the == $null comparison work ?
script example
my_function("some param","$var(result)");
if( $var(result) == $null {
do something
}
in code => dst_pv->setf(msg, &dst_pv->pvp, (int)EQ_T, &dst_val);
should the comparison work if we set dst_val.flags = PV_VAL_NULL ?
if( $(myPvar{my.mytransform,transformParameter}) == $null) {
....
}
should this work if the transform returns val.flags = PV_VAL_NULL ?
thank you
