No checking is done. Mismatches can -cause random crashes. +cause random crashes. API-level access, on the other hand, is safer. +Speed-wise, API-level access is much faster (it is common to have +the opposite misconception about performance). Note that only functions and global variables live in library objects; the types exist in the ``ffi`` instance independently of library objects. _______________________________________________ pypy-commit mailing list pypy-commit@python.org https://mail.python.org/mailman/listinfo/pypy-commit
