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 set- ting, 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.
