.IP CURLOPT_WILDCARDMATCH
Set this option to 1 if you want to transfer multiple files according to a
file name pattern. The pattern can be specified as part of the \fICURLOPT_URL\fP
option, using an fnmatch-like pattern (Shell Pattern Matching) in the last part
of URL (file name).

By default, libcurl uses its internal implementation of fnmatch(). You can
provide your own matching function by the \fICURLOPT_FNMATCH_FUNCTION\fR option.

This feature is only supported by the FTP download for now.
A brief introduction of its syntax follows:

.IP "\fB*\fR - ASTERISK"
\&ftp://example.com/some/path/\fB*.txt\fR (for all txt's from the root
.IP "\fB*\fP - ASTERISK"
\&ftp://example.com/some/path/\fB*.txt\fP (for all txt's from the root
directory)
.RE
.RS
.IP "\fB?\fR - QUESTION MARK"
.IP "\fB?\fP - QUESTION MARK"
Question mark matches any (exactly one) character.

.IP "\fB[\fR - BRACKET EXPRESSION"
.IP "\fB[\fP - BRACKET EXPRESSION"
The left bracket opens a bracket expression. The question mark and asterisk have
no special meaning in a bracket expression. Each bracket expression ends by the
right bracket and matches exactly one character. Some examples follow:
\fB[a-zA-Z0\-9]\fR or \fB[f\-gF\-G]\fR \- character interval
\fB[a-zA-Z0\-9]\fP or \fB[f\-gF\-G]\fP \- character interval
\fB[abc]\fR - character enumeration
\fB[abc]\fP - character enumeration
\fB[^abc]\fR or \fB[!abc]\fR - negation
\fB[^abc]\fP or \fB[!abc]\fP - negation
\fB[[:\fR\fIname\fR\fB:]]\fR class expression. Supported classes are
\fBalnum\fR,\fBlower\fR, \fBspace\fR, \fBalpha\fR, \fBdigit\fR, \fBprint\fR,
\fBupper\fR, \fBblank\fR, \fBgraph\fR, \fBxdigit\fR.

\fB[][-!^]\fR - special case \- matches only '\-', ']', '[', '!' or '^'. These
\fB[][-!^]\fP - special case \- matches only '\-', ']', '[', '!' or '^'. These
characters have no special purpose.
\fB[\\[\\]\\\\]\fR - escape syntax. Matches '[', ']' or '\\'.

Using the rules above, a file name pattern can be constructed:
