Hi

I’m having a some problems in my application.

I have a non photon application, connecting to photon with PtInit()
At a point in the application, i load a library and call a function from
it, if i understand right, i should not be forced to reinit my
connection to Photon…
and sure, that works fine, i’m able to use a Ph* func and it give
expected results, Wnen i’m trying to use PtConnectFindName, it segfault,
as it normally do when you havn’t done PtInit… i tried PtInit again in
the func from the runtime lib, and sure, no segfault from
PtConnectFindName now, but it return NULL…
I have tried using this func as a standalone test program, and then it
works great.

Anyone have any ideas? any suggestions or ideas is appriciated.
Thanks alot

Hi Johan,

Would it be possible to upload a small test case for this application
to the newsgroup that demonstrates the problem ??
Maybe less than 100 lines of code in two .c files and a
makefile… :slight_smile:

Hi again, sorry for the delay in answering.

I looked at this again, tried to narrow down the problem so it would fit
in less then 100 lines :smiley: well , I discoverd the runtime dll is not the
problem, but since i’m using Name_attach() in my code… i searched for
this in the helpviewer and discoverd it was a known problem, or whatever
to call it…

Thanks alot for the help :slight_smile:
