CURLOPT_WILDCARDMATCH(3) curl_easy_setopt options CURLOPT_WILDCARDMATCH(3)NAMECURLOPT_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 Match‐
ing) 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_FUNC‐
TION(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 con‐
structed:
ftp://example.com/some/path/[a-z[:upper:]\\].jpeg
