double fmemcmp(const void *data1, size_t size1, const void *data2, size_t size2);

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

The fmemcmp function returns a floating point value between 0.0 and FSTRCMP_IDENTICAL.  A value of 0.0 means the memory areas are utterly un-alike.  A value of FSTRCMP_IDENTICAL means the memory areas 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.
