! 30: CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_USE_EPSV, long epsv);
! 31: .SH DESCRIPTION
! 32: Pass \fIepsv\fP as a long. If the value is 1, it tells curl to use the EPSV
! 33: command when doing passive FTP downloads (which it does by default). Using
! 34: EPSV means that it will first attempt to use EPSV before using PASV, but if
! 35: you pass zero to this option, it will not try using EPSV, only plain PASV.
! 36:
! 37: If the server is an IPv6 host, this option will have no effect as of 7.12.3.
