I have some class that hold pointer on the data writer.
On my init function i fine the data writer by name - and i set the pointer to this data writer.
Now, when i try to use this pointer -- i get exception that the writer is close.
when i check the address value i see that its valid address and not null.
what to do ?
( code is modern C++ )
Hi Yanshof,
Could you share the relevant snippets of code?
One thing that comes to mind is that it might be necessary to call
retain()
on the DataWriter.Explained here https://community.rti.com/static/documentation/connext-dds/current/doc/api/connext_dds/api_cpp2/group__DDSCpp2Conventions.html#a_st_ref_type,
the DataWriter entity may be being destroyed if there are no references to it.
If you do use
DataWriter.retain()
, you will need to callDataWriter.close()
when you want to destroy it (as it will no longer be automatically destroyed).Sam
