CURLOPT_FTP_FILEMETHOD(3) curl_easy_setopt options 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 compli-
ant 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 op-
erates 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,
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.
