CURLOPT_WILDCARDMATCH(3)				     curl_easy_setopt options					  CURLOPT_WILDCARDMATCH(3)

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 CUR-
       LOPT_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  CUR-
       LOPT_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)

	      ? - 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

PROTOCOLS

       This feature is only supported for FTP download.

EXAMPLE

       See https://curl.haxx.se/libcurl/c/ftp-wildcard.html

AVAILABILITY

       Added in 7.21.0

RETURN VALUE

       Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
