example of libtiff

Also, I took a look to the code of libtiff that is also included in msys2:

#ifdef __WIN32__
#include <windows.h>
 * Open a TIFF file with a Unicode filename, for read/writing.
TIFFOpenW(const wchar_t* name, const char* mode)
	static const char module[] = "TIFFOpenW";
	int m, fd;
	int mbsize;
	char *mbname;
	TIFF* tif;
	m = _TIFFgetMode(mode, module);
	if (m == -1)
		return ((TIFF*)0);
