fstrcoll: fuzzy comparison of two strings using the current locale
NAMEfstrcoll - fuzzy comparison of two strings using the current locale
DESCRIPTIONThe 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.
RETURN VALUEThe 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.
