Not at all unless they are somehow accessible through Python objects. A  
way to export C APIs through Python objects is the CObject, which  
doesn't do anything useful at the Python level but stores pointers and  
makes them accessible to other modules through the import mechanism. If  
mmap (or any other module) doesn't create such objects, you can try to  
add the necessary code and convince the original module author to  
accept the addition.
