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 effectively breaks
       that feature.

DEFAULT

       0, disabled

PROTOCOLS

       FTP, SFTP and POP3

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/dir/");

           /* list only */
           curl_easy_setopt(curl, CURLOPT_DIRLISTONLY, 1L);

           res = curl_easy_perform(curl);

           curl_easy_cleanup(curl);
         }
       }
