The function you want is comptypes.
Thanks. That is working well.
Hi Brendon, Wouldn't the C++ one (mostly) be a superset of the C?
Types are reasonably different between the C and C++ front ends though you do have the common ones because as you said, C++ is a superset of C. The C++ front end has a similar comptypes function which is called by same_type_p, however it is not the same as the C one. Rather than trying to write my own based on the C++ one, I was sure there would already exist a function to do it somewhere in the C front end... Thanks for the help. Brendon.
