.SH NAME
fstrcmp \- fuzzy comparison of two strings
.if require_index \{
.XX "fstrcmp(3)" "fuzzy comparison of two strings"
.\}
.SH SYNOPSIS
#include <fstrcmp.h>
.sp 0.3
#define FSTRCMP_IDENTICAL
.br
#define FSTRCMP_THRESHOLD
.br
#define FSTRCMP_ERROR
.sp 0.3
double fstrcmp(const char *string1, const char *string2);
.SH DESCRIPTION
The \f[B]fstrcmp\fP() function compares the two strings,
\f[I]string1\fP and \f[I]string2\fP.
.SH RETURN VALUE
The \f[B]fstrcmp\fP 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.
.PP
A value of FSTRCMP_ERROR (always negative) indicates a \f[I]malloc\fP(3)
failure.
