fstrcoll — fuzzy comparison of two strings using the current locale
double fstrcoll(const char *string1, const char *string2);
The strcoll() function compares the two strings sting1 and string2. The comparison is based on strings interpreted as appropriate for the program's current locale for category LC_CTYPE.
The fstrcoll function returns a floating point value between 0.0 and FSTRCMP_IDENTICAL. A value of 0.0 means the strings are utterly un-alike. A value of FSTRCMP_IDENTICAL means the 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) or mbstowcs(3) failure.
