CURLOPT_QUOTE - (S)FTP commands to run before transfer
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_QUOTE, struct curl_slist *cmds);
Pass a pointer to a linked list of FTP or SFTP commands to pass to the server prior to your request. This is done before any other commands are issued (even before the CWD command for FTP). The linked list should be a fully valid list of 'struct curl_slist' structs properly filled in with text strings. Use curl_slist_append(3) to append strings (commands) to the list, and clear the entire list afterwards with curl_slist_free_all(3).
Disable this operation again by setting a NULL to this option.
When speaking to an FTP server, prefix the command with an asterisk (*) to make libcurl continue even if the command fails as by default libcurl stops at first failure.
The set of valid FTP commands depends on the server (see RFC 959 for a list of mandatory commands).
libcurl does not inspect, parse or "understand" the commands passed to the server using this option. If you change connection state, working directory or similar using quote commands, libcurl does not know about it.
The path arguments for FTP or SFTP can use single or double quotes to distinguish a space from being the parameter separator or being a part of the path. e.g. rename with sftp using a quote command like this:
"rename 'test/_upload.txt' 'test/Hello World.txt'"
NULL
SFTP and FTP
int main(void) { struct curl_slist *cmdlist = NULL; cmdlist = curl_slist_append(cmdlist, "RNFR source-name"); cmdlist = curl_slist_append(cmdlist, "RNTO new-name"); CURL *curl = curl_easy_init(); if(curl) { CURLcode res; curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/foo.bin"); /* pass in the FTP commands to run before the transfer */ curl_easy_setopt(curl, CURLOPT_QUOTE, cmdlist); res = curl_easy_perform(curl); curl_easy_cleanup(curl); } }
SFTP support added in 7.16.3. *-prefix for SFTP added in 7.24.0
Returns CURLE_OK
