CURLOPT_FTP_FILEMETHOD(3)           libcurl          CURLOPT_FTP_FILEMETHOD(3)

NAME
       CURLOPT_FTP_FILEMETHOD - select directory traversing method for FTP

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_FILEMETHOD,
                                 long method);

DESCRIPTION
       Pass a long telling libcurl which method to use to reach a file on a
       FTP(S) server.

       This option exists because some server implementations are not
       compliant to what the standards say should work.

       The argument should be one of the following alternatives:

       CURLFTPMETHOD_MULTICWD
              libcurl does a single CWD operation for each path part in the
              given URL. For deep hierarchies this means many commands. This
              is how RFC1738 says it should be done. This is the default but
              the slowest behavior.

       CURLFTPMETHOD_NOCWD
              libcurl does no CWD at all. libcurl will do SIZE, RETR, STOR etc
              and give a full path to the server for all these commands. This
              is the fastest behavior.

       CURLFTPMETHOD_SINGLECWD
              libcurl does one CWD with the full target directory and then
              operates on the file "normally" (like in the multicwd case).
              This is somewhat more standards compliant than 'nocwd' but
              without the full penalty of 'multicwd'.

DEFAULT
       CURLFTPMETHOD_MULTICWD

PROTOCOLS
       FTP

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/1/2/3/4/new.txt");
         curl_easy_setopt(curl, CURLOPT_FTP_FILEMETHOD,
                          (long)CURLFTPMETHOD_SINGLECWD);

         ret = curl_easy_perform(curl);

         curl_easy_cleanup(curl);
       }

AVAILABILITY
       Added in 7.15.1

RETURN VALUE
       Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION
       if not.
