CURLOPT_PROXY_TRANSFER_MODE(3) | curl_easy_setopt options | 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¶
FTP over proxy
EXAMPLE¶
CURL *curl = curl_easy_init(); if(curl) {
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);
ret = curl_easy_perform(curl);
curl_easy_cleanup(curl); }
AVAILABILITY¶
Added in 7.18.0
RETURN VALUE¶
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if the enabled value is not supported.
