       The fstrcmp() function compares the two strings, string1 and string2, ignoring case.

       fstrcasecmpi - fuzzy comparison of two strings ignoring case

       The  fstrcasecmpi function returns an int value between 0 and FSTRCMPI_IDENTICAL.  A value of 0 means the
       strings are utterly un-alike.  A value of FSTRCMPI_IDENTICAL means the strings are identical.  A value of
       more than FSTRCMPI_THRESHOLD (it lies between 0 and FSTRCMPI_IDENTICAL) would be considered "similar"  by
       most people.

       A value of FSTRCMPI_ERROR (always negative) indicates a malloc(3) failure.
