fstrcmp(3)

NAME
fstrcmp - fuzzy comparison of two strings

SYNOPSIS
#include <fstrcmp.h>

#define FSTRCMP_IDENTICAL
#define FSTRCMP_THRESHOLD
#define FSTRCMP_ERROR

double fstrcmp(const char *string1, const char *string2);

DESCRIPTION
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.
