CURLOPT_PROXY_TRANSFER_MODE(3) | Library Functions Manual | CURLOPT_PROXY_TRANSFER_MODE(3) |
NAME
CURLOPT_PROXY_TRANSFER_MODE - append FTP transfer mode to URL for proxy
SYNOPSIS
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_TRANSFER_MODE, long enabled);
DESCRIPTION
Pass a long. If the value is set to 1 (one), it tells libcurl to set the transfer mode (binary or ASCII) for FTP transfers done via an HTTP proxy, by appending ;type=a or ;type=i to the URL. Without this setting, or it being set to 0 (zero, the default), CURLOPT_TRANSFERTEXT(3) has no effect when doing FTP via a proxy. Beware that not all proxies support this feature.
DEFAULT
0, disabled
PROTOCOLS
This functionality affects all supported protocols
EXAMPLE
int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode res; curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/old-server/file.txt"); curl_easy_setopt(curl, CURLOPT_PROXY, "http://localhost:80"); curl_easy_setopt(curl, CURLOPT_PROXY_TRANSFER_MODE, 1L); curl_easy_setopt(curl, CURLOPT_TRANSFERTEXT, 1L); res = curl_easy_perform(curl); curl_easy_cleanup(curl); } }
AVAILABILITY
Added in curl 7.18.0

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if the enabled value is not supported.
