plucky (3) CURLOPT_PROXY_TRANSFER_MODE.3.gz

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);
         }
       }
