CURLOPT_FTP_FILEMETHOD(3) Library Functions Manual 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 RFC 1738 says it should be done. This is the default but the slowest be- havior. 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 oper- ates 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 result; curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/1/2/3/4/new.txt"); curl_easy_setopt(curl, CURLOPT_FTP_FILEMETHOD, CURLFTPMETHOD_SINGLECWD); result = curl_easy_perform(curl); curl_easy_cleanup(curl); } } HISTORY CURLFTPMETHOD_* enums became long types in 8.16.0, prior to this version a long cast was necessary when passed to curl_easy_setopt(3). 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).
