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
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:
- [ - 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
