+# NAME
+
+CURLOPT_FTP_USE_PRET - use PRET for FTP
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_USE_PRET, long enable);
+~~~
+
+# DESCRIPTION
+
+Pass a long. If the value is 1, it tells curl to send a PRET command before
+PASV (and EPSV). Certain FTP servers, mainly drftpd, require this non-standard
+command for directory listings as well as up and downloads in PASV mode. Has
+no effect when using the active FTP transfers mode.
+
+# DEFAULT
+
+0
+
+# %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");
+
+    /* a drftpd server, do it */
+    curl_easy_setopt(curl, CURLOPT_FTP_USE_PRET, 1L);
+
+    res = curl_easy_perform(curl);
+
+    curl_easy_cleanup(curl);
+  }
+}
+~~~

+curl_easy_setopt(3) returns a CURLcode indicating success or error.
