- make DEFAULT sections less repetitive - make historic mentions use HISTORY - generate the protocols section on `# %PROTOCOLS%` instead of guessing where to put it - generate the availability section on `# %AVAILABILITY%` instead of guessing where to put it - make the protocols section more verbose Closes #14227

# 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'.
|
|
|
|
# DEFAULT
|
|
|
|
CURLFTPMETHOD_MULTICWD
|
|
|
|
# %PROTOCOLS%
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
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%

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