SYNOPSIS


#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_USE_PRET, long enable);

DESCRIPTION

CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL,
"ftp://example.com/old-server/file.txt");

/* a drftpd server, do it */
curl_easy_setopt(curl, CURLOPT_FTP_USE_PRET, 1L);

res = curl_easy_perform(curl);

curl_easy_cleanup(curl);
}
}
