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. .SH SEE ALSO .TP 8n \f[I]fmemcmp\fP(3) fuzzy comparison of two memory areas .TP 8n \f[I]fstrcasecmp\fP(3) fuzzy comparison of two strings ignoring case .TP 8n \f[I]fstrcmpi\fP(3) fuzzy comparison of two strings .TP 8n \f[I]strcmp\fP(3) compare two strings .lf 1 ./man/man1/z_copyright.so .\" .\" fstrcmp - fuzzy string compare library .\" Copyright (C) 2009 Peter Miller .\" Written by Peter Miller .\" .\" This program is free software; you can redistribute it and/or modify .\" it under the terms of the GNU General Public License as published by .\" the Free Software Foundation; either version 3 of the License, or .\" (at your option) any later version. .\" .\" This program is distributed in the hope that it will be useful, .\" but WITHOUT ANY WARRANTY; without even the implied warranty of .\" MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
