Re: Getting the jBase DP (data pointer) of the current session when using pure C

2020-03-09 Thread Igor Osmolovskiy 
Thank you Peter

But do you think it is still possible to retrieve a DP for an existing 
session? 
It can be seen that no new session is created when a JBC program is being 
called in jshell e.g. Therefore a DP initialization is happening somehow 
for that case
Thanks

Re: Getting the jBase DP (data pointer) of the current session when using pure C

2020-03-09 Thread Peter Falson 
If you want to use python in this mix then I would think you need to call 
python from jBASE so you can persist the dp.

RE: Getting the jBase DP (data pointer) of the current session when using pure C

2020-03-09 Thread Dan Ell 
That would be because the jsh initiated the thread and the program running 
under it is a shared object /dll beneath that thread.

Re: Getting the jBase DP (data pointer) of the current session when using pure C

2020-03-09 Thread Igor Osmolovskiy 
This approach works, i.e. if we use a JBC program to call a Python that 
would call a C written extension module then DP is just passed and no 
additional session is being created.
But would be great not to use JBC as a starting point

Re: Getting the jBase DP (data pointer) of the current session when using pure C

2020-03-09 Thread Igor Osmolovskiy 
Hello Dan
Right, but is there a possibility to avoid creating a new thread? 
One option proposed by Peter is to launch Pyhton from JBC e.g. But any 
chance to achieve this for pure Pyhton?

Re: Getting the jBase DP (data pointer) of the current session when using pure C

2020-03-09 Thread Peter Falson 
Your only choices are start from jsh/jbc call python, call jbc etc or start 
with python call jbc. 

Either way the dp needs to be carried around. 

I can post an example of calling python (it needs jBASE 5).
