Unicode open

[WindowsNT]

In Windows, it's essential to be able to open unicode paths. I 've altered it to this:

TSFDEF tsf* tsf_load_filename(const wchar_t* filename)
{
	tsf* res;
	struct tsf_stream stream = { TSF_NULL, (int(*)(void*,void*,unsigned int))&tsf_stream_stdio_read, (int(*)(void*,unsigned int))&tsf_stream_stdio_skip };
	#if __STDC_WANT_SECURE_LIB__
	FILE* f = TSF_NULL; _wfopen_s(&f, filename, L"rb");
	#else
	FILE* f = _wfopen(filename, L"rb");
	#endif
	if (!f)
	{
		//if (e) *e = TSF_FILENOTFOUND;
		return TSF_NULL;
	}
	stream.data = f;
	res = tsf_load(&stream);
	fclose(f);
	return res;
}

The library can't use platform specific functions like that so we're limited to offering the fopen variant. The official way to do this would be to use tsf_load directly in your application. Something like:

int main(int argc, char *argv[])
{
	struct TSFStream
	{
		static int Read(FILE* f, void* ptr, unsigned int size) { return (int)fread(ptr, 1, size, f); }
		static int Skip(FILE* f, unsigned int count) { return !fseek(f, count, SEEK_CUR); }
	};
	tsf_stream stream = { TSF_NULL, (int(*)(void*,void*,unsigned int))&TSFStream::Read, (int(*)(void*,unsigned int))&TSFStream::Skip };
	FILE* f = TSF_NULL;
	_wfopen_s(&f, L"file.sf2", L"rb");
	g_TinySoundFont = tsf_load(&stream);
	fclose(f);

	...
}

But of course you're free to change the library as you did.

If that seems too annoying, maybe the library could offer a new function that takes a FILE* instead of a path directly?

// in tsf.h
TSFDEF tsf* tsf_load_file(FILE* f);

// in a program
int main(int argc, char *argv[])
{
	FILE* f = _wfopen(L"path.sf2", L"rb")
	tsf* sf = tsf_load_file();
	fclose(f);

	...
}
