int ntfs_ucsncmp (const ntfschar * s1, const ntfschar * s2, size_t n);
Compare the first n characters of the Unicode strings s1 and s2, The strings in little endian format and appropriate le16_to_cpu conversion is performed on non-little endian machines.
The function returns an integer less than, equal to, or greater than zero if s1 (or the first n Unicode characters thereof) is found, respectively, to be less than, to match, or be greater than s2.
