[cffi-devel] Re: stdcall example (was: CFFI 0.9.0 Release)

Please find attached two variations of the same test, which is to invoke the EnumWindows Win32 API with a callback that simply prints a message confirming that it was called (which occurs once for each top-level window).

After loading either of these files, run (callback-test) to execute the test.

stdcall-test-clisp.lisp uses the CLISP FFI. Note that it specifies :stdc-stdcall as the calling convention. This test executes correctly as expected.

stdcall-test-cffi.lisp is the same but written in CFFI terms, except that stdcall is not available. This variant will crash clisp -- although circumstances may vary, so you probably need to execute (callback-test) in a loop to be sure.
