NAME
       CURLOPT_WILDCARDMATCH - enable directory wildcard transfers

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_WILDCARDMATCH, long
       onoff);

DESCRIPTION
       Set onoff to 1 if you want to transfer multiple files according to a
       file name pattern. The pattern can be specified as part of the
       _URL&section=3">CURLOPT_URL(3) option, using an fnmatch-like pattern (Shell Pattern
       Matching) in the last part of URL (file name).

       By default, libcurl uses its internal wildcard matching implementation.
       You can provide your own matching function by the
       _FNMATCH_FUNCTION&section=3">CURLOPT_FNMATCH_FUNCTION(3) option.

       A brief introduction of its syntax follows:

              * - ASTERISK
                     ftp://example.com/some/path/*.txt (for all txt's from the
                     root directory). Only two asterisks are allowed within
                     the same pattern string.

              ? - QUESTION MARK
                     Question mark matches any (exactly one) character.

                     ftp://example.com/some/path/photo?.jpeg

              [ - 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:

                     [a-zA-Z0-9] or [f-gF-G] - character interval

                     [abc] - character enumeration

                     [^abc] or [!abc] - negation

                     [[:name:]] class expression. Supported classes are
                     alnum,lower, space, alpha, digit, print, upper, blank,
                     graph, xdigit.

                     [][-!^] - special case - matches only '-', ']', '[', '!'
                     or '^'. These characters have no special purpose.

                     [\[\]\\] - escape syntax. Matches '[', ']' or '\'.

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

                     ftp://example.com/some/path/[a-z[:upper:]\\].jpeg
