Name

Synopsis

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DIRLISTONLY, long listonly);

Description

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.
