fstrcmp3
Fuzzy comparison of two strings
Usage
#include <fstrcmp.h>
#define FSTRCMP_IDENTICAL
#define FSTRCMP_THRESHOLD
#define FSTRCMP_ERROR
double fstrcmp(const char *string1, const char *string2);
Overview
The fstrcmp() function compares the two strings, string1 and string2.
Return value
The fstrcmp function returns a floating point value between 0.0 and FSTRCMP_IDENTICAL. A value of 0.0 means the strings are utterly un-alike. A value of FSTRCMP_IDENTICAL means the strings 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.
