CURLOPT_DIRLISTONLY(3) curl_easy_setopt options CURLOPT_DIRLISTONLY(3) NAME CURLOPT_DIRLISTONLY - ask for names only in a directory listing SYNOPSIS #include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DIRLISTONLY, long listonly); DESCRIPTION For FTP and SFTP based URLs a parameter set to 1 tells the library to list the names of files in a directory, rather than performing a full directory listing that would normally include file sizes, dates etc. For POP3 a parameter of 1 tells the library to list the email message or messages on the POP3 server. This can be used to change the default behavior of libcurl, when combined with a URL that contains a message ID, to perform a "scan listing" which can then be used to determine the size of an email. Note: For FTP this causes a NLST command to be sent to the FTP server. Beware that some FTP servers list only files in their response to NLST; they might not include subdirectories and symbolic links. Setting this option to 1 also implies a directory listing even if the URL does not end with a slash, which otherwise is necessary. Do NOT use this option if you also use CURLOPT_WILDCARDMATCH(3) as it will effectively break that feature then. DEFAULT 0, disabled PROTOCOLS FTP, SFTP and POP3 EXAMPLE CURL *curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/dir/"); /* list only */ curl_easy_setopt(curl, CURLOPT_DIRLISTONLY, 1L); ret = curl_easy_perform(curl); curl_easy_cleanup(curl); } AVAILABILITY This option was known as CURLOPT_FTPLISTONLY up to 7.16.4. POP3 is sup- ported since 7.21.5. RETURN VALUE Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
