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);
       }
