fwcscmp — fuzzy comparison of two wide-character strings
double fwcscmp(const wchar_t *string1, const wchar_t *string2);
The fwcscmp() function compares the two wide-character strings, string1 and string2.
The fwcscmp function returns a floating point value between 0.0 and FSTRCMP_IDENTICAL. A value of 0.0 means the two wide-character strings are utterly un-alike. A value of FSTRCMP_IDENTICAL means the two wide-character strings are identical. A value of more than FSTRCMP_THRESHOLD (it lies between 0.0 and FSTRCMP_IDENTICAL) would be considered "similar" by most people.
A value of FSTRCMP_ERROR (always negative) indicates a malloc(3) failure.
