fmemcmp(3) Library Functions Manual fmemcmp(3)
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.
