Thread Subject: Accessing mexw32 from C/C++

A lot of stuff is written about how to access mexw32 files
from MatLab/Simulink. However I haven't found anything about
accessing mexw32 (created by RTW) from C/C++. A simple try
already failed at the LoadLibrary function. Has anybody done
this before?

Thanks

Hi Markus,

If you are referring to MEX-functions generated by the EMLMEX command, then
these are not designed to be used outside the MATLAB environment. If you
have a Real-Time Workshop license you can use EMLC with the -T RTW:lib to
generate a standalone library. This can be linked into your application
however you wish. Of course, your library won't be able make calls using
eml.extrinsi in this case.

Hi Fred,

Thanks for your answer. What I actually did is right
clicking on a subsystem and go to Real Time
Workshop|Generate S-Function ... I would like to acces the
mexw32 file, created this way in MSVC++ 7.0. With MatLab
2007b, not even the LoadLibray function worked. I also have
a 2006a MatLab Version on my computer, and the LoadLibrary
function worked, with the Mexw32 file created with
MatLab/Simulink 2006a.
I was hoping to find the usual level 2 S-function interface
(i.e. mdlInitializeSizes, mdlInitializeSampleTimes,
mdlStart, mdlOutputs, mdlUpdate and mdlTerminate) however
the GetProcAddress calls with the previously mentioned
functions all gave a NULL pointer back, i.e. could not find
those functions.
What I need now is a description of the interface of a
mexw32 file created with RTW.
If you're interested, I'll be happy to send you the code I
have so far.

Thanks
Markus
