This has been mentioned here several times already in other threads. In this case you are not calling open(1), but some function pointer. And therefore it is undesirable to let it be expanded as function-like macro (which POSIX allows). The right fix is to use one of: retval = (test_io_backing_manager->open)(name, flags, &data->real); retval = (*test_io_backing_manager->open)(name, flags, &data->real); retval = test_io_backing_manager->(open)(name, flags, &data->real); or, far less desirable, but what standard allows, #undef open above this. The last one means that no open(1) error checking will be done in the rest of the source file, which is not a good idea.
I've gone with the last of these suggestions for alsa-oss, partly because that's what someone (lpoetter?) chose to do for alsa-lib. Bad practice, perhaps, but the standard disclaimer applies: patches accepted. ;-)
