fmemcmpi — fuzzy comparison of two memory areas

Synopsis

#include <fstrcmp.h>

#define FSTRCMPI_IDENTICAL
#define FSTRCMPI_THRESHOLD
#define FSTRCMPI_ERROR

int fmemcmpi(const void *data1, size_t size1, const void *data2, size_t size2);

Description

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

Return Value

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.
