# NAME
|

|
|
|

|
|
CURLOPT_FTP_FILEMETHOD - select directory traversing method for FTP

# SYNOPSIS
|

|
|
|
||
|
|
~~~c
|
||
|
|
#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'.
|
||
|
|
|
||
|

||
|

CURLFTPMETHOD_MULTICWD
