Is it possible that the XPRESS c-libraries can be called directly from Python using ctypes?

 I have successfully called a C dll from Python (using ctypes) that calls XPRMInit, XPRMloadmod etc but it would be nice to avoid the need to create the DLL altogether and call these functions direc...

Hi Susanne, you were right: I have not noticed that 8.6 started enforcing the 'public' marker (I did not even know there was such a marker). Once I added it to the Mosel model, the Python code as expected - thanks!

You are also right that Johannes' example did not use XPRMfindident - I have added support for more functions from C library and have not noticed that this was one of those. The code itself is simple enough:

def findident(model, name):
    returned = c_void_p()
    objType = lib.XPRMfindident(model, name.encode(), byref(returned))
    return objType, returned

And yes, i would be willing to share my extension of the code, with the understanding that it is just an extension of an example (not a full module), written by someone wihtout much experience with Python...

Are you thinking github, or do you have some more suitable place?
