Indeed, this works in CFFI, but RFFI is by far not as nice as that. You need to build the array value manually with "ar=lltype.new(ARRAY_OF_VOIDP.TO, length, flavor='raw'); ar[0]=a; " etc., remembering to do "lltype.free(ar, flavor='raw')" at the end. Or use "with lltype.scoped_alloc(...)", which replaces both the malloc at the start and the free at the end. A bientôt, Armin. _______________________________________________ pypy-dev mailing list pypy-dev@python.org https://mail.python.org/mailman/listinfo/pypy-dev
