CURLOPT_FTP_FILEMETHOD(3) Introduction to Library Functions

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 RFC 1738 says it should be done. This is the default
but the slowest behavior.

CURLFTPMETHOD_NOCWD
libcurl makes no CWD at all. libcurl does SIZE, RETR, STOR etc
and gives a full path to the server for all these commands.
This is the fastest behavior since it skips having to change
directories.

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

This functionality affects ftp only

EXAMPLE

int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
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);

res = curl_easy_perform(curl);

curl_easy_cleanup(curl);
}
}

AVAILABILITY

Added in curl 7.15.1

RETURN VALUE

curl_easy_setopt(3) returns a CURLcode indicating success or error.

CURLE_OK (0) means everything was OK, non-zero means an error
occurred, see libcurl-errors(3).
