fstrcmpi

fstrcmpi(3)						     Library Functions Manual						       fstrcmpi(3)

NAME

       fstrcmpi - fuzzy comparison of two strings

SYNOPSIS

       #include <fstrcmp.h>
       #define FSTRCMPI_IDENTICAL
       #define FSTRCMPI_THRESHOLD
       #define FSTRCMPI_ERROR
       int fstrcmpi(const char *string1, const char *string2);

DESCRIPTION

       The fstrcmpi() function compares the two strings, string1 and string2.

RETURN VALUE

       The fstrcmpi function returns an int value between 0 and FSTRCMPI_IDENTICAL.  A value of 0 means the strings are utterly un-alike.  A value
       of FSTRCMPI_IDENTICAL means the strings are identical.  A value of more than FSTRCMPI_THRESHOLD (it lies between 0 and  FSTRCMPI_IDENTICAL)
       would be considered "similar" by most people.

       A value of FSTRCMPI_ERROR (always negative) indicates a malloc(3) failure.
