Thanks for your reply!
Drawing on the plugin.c, I remove the BASS_ASYNCFILE tag. And the error disappears. But why?
before:
_fstream = _bass.BASS_StreamCreateFile(FALSE, pathPointer, 0, 0, BASS_UNICODE | BASS_ASYNCFILE | BASS_SAMPLE_FLOAT);
now:
_fstream = _bass.BASS_StreamCreateFile(
FALSE, pathPointer, 0, 0, BASS_UNICODE | BASS_SAMPLE_FLOAT);
