NAME

       fmemcmp - fuzzy comparison of two memory areas

SYNOPSIS

       #include <fstrcmp.h>
       #define FSTRCMP_IDENTICAL
       #define FSTRCMP_THRESHOLD
       #define FSTRCMP_ERROR
       double fmemcmp(const void *data1, size_t size1, const void *data2, size_t size2);

DESCRIPTION

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

RETURN VALUE

       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.
