23 .TH CURLOPT_DIRLISTONLY 3 "May 05, 2017" "libcurl 7.59.0" "curl_easy_setopt options"
26 CURLOPT_DIRLISTONLY \- ask for names only in a directory listing
28 #include <curl/curl.h>
30 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DIRLISTONLY, long listonly);
32 For FTP and SFTP based URLs a parameter set to 1 tells the library to list the
33 names of files in a directory, rather than performing a full directory listing
34 that would normally include file sizes, dates etc.
36 For POP3 a parameter of 1 tells the library to list the email message or
37 messages on the POP3 server. This can be used to change the default behaviour
38 of libcurl, when combined with a URL that contains a message ID, to perform a
39 "scan listing" which can then be used to determine the size of an email.
41 Note: For FTP this causes a NLST command to be sent to the FTP server. Beware
42 that some FTP servers list only files in their response to NLST; they might not
43 include subdirectories and symbolic links.
45 Setting this option to 1 also implies a directory listing even if the URL
46 doesn't end with a slash, which otherwise is necessary.
48 Do NOT use this option if you also use \fICURLOPT_WILDCARDMATCH(3)\fP as it
49 will effectively break that feature then.
56 CURL *curl = curl_easy_init();
58 curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/dir/");
61 curl_easy_setopt(curl, CURLOPT_DIRLISTONLY, 1L);
63 ret = curl_easy_perform(curl);
65 curl_easy_cleanup(curl);
69 This option was known as CURLOPT_FTPLISTONLY up to 7.16.4. POP3 is supported
72 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
