       The  fmemcmpi() function compares the two memory areas, the size1 bytes pointed to by data1 and the size2
       bytes pointed to by data2.

       fmemcmpi - fuzzy comparison of two memory areas

       The fmemcmpi function returns an int value between 0 and FSTRCMPI_IDENTICAL.  A  value  of  0  means  the
       memory  areas  are utterly un‐alike.  A value of FSTRCMPI_IDENTICAL means the memory areas are identical.
       A value of more than FSTRCMPI_THRESHOLD (it lies between 0.0 and FSTRCMP_IDENTICAL) would  be  considered
       "similar" by most people.

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