I am using R2019b version of Matlab and integrating the Matlab engine API into legacy C code using MS VS 2008 (compiled to 64 bit). When issuing a Matlab command to run a program using the engEvalString(..) command I found that the command is blocking (synchronous) in the C code, example:
engEvalString(ep,"my_m_code");
or
engEvalString(ep,"pause(10)");
Is there a way to issue an asynchronous Matlab command from C so that it is non-blocking on the C code side? Or is there a way to start the Matlab engine from C code so that it runs asynchronously.
The C code passes Numeric Matrix data to matlab using the function engPutVariable(..) and it (C code) is very time sensitive in it's task and can only be minimaly blocked by Matlab's process.
Thanks for your input

I was able to compile the legacy C code in C++ (VS 2008) but as per my understanding I need to use the Matlab library libMatlabEngine.lib which requires c++ 11 to create async calls to Matlab from C++ (maybe I'm wrong here). Unfortunately I've NOT been able to find an example.
The approach of using multi threads and a queue in C is appealing but again I've not been able to find an example. If you have knowledge of sample code which could help I would grestly appreciate it.

Yes I think Matlab currently requires minimum VS 2015. I don't have any examples available.
