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 speci-
fied as part of the 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 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)
? - 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.
