- Ingmar Runge enhanced libcurl's FTP engine to support the PRET command. This

  command is a special "hack" used by the drftpd server, but even though it is

  a custom extension I've deemed it fine to add to libcurl since this server

  seems to survive and people keep using it and want libcurl to support

  it. The new libcurl option is named CURLOPT_FTP_USE_PRET, and it is also

  usable from the curl tool with --ftp-pret. Using this option on a server

  that doesn't support this command will make libcurl fail.

  I added test cases 1107 and 1108 to verify the functionality.

  The PRET command is documented at

connection. (Added in 7.14.2)

This option has no effect if PORT, EPRT or EPSV is used instead of PASV.

.IP "--ftp-pret"

(FTP) Tell 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.

(Added in 7.20.x)

.IP "--ftp-ssl"

(FTP) Try to use SSL/TLS for the FTP connection.  Reverts to a non-secure

connection if the server doesn't support SSL/TLS.  See also

pass zero to this option, it will not try using EPSV, only plain PASV.

If the server is an IPv6 host, this option will have no effect as of 7.12.3.

.IP CURLOPT_FTP_USE_PRET

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.

(Added in 7.20.x)

.IP CURLOPT_FTP_CREATE_MISSING_DIRS

Pass a long. If the value is 1, curl will attempt to create any remote

directory that it fails to CWD into. CWD is the command that changes working

.IP "CURLE_FTP_WEIRD_227_FORMAT (14)"

FTP servers return a 227-line as a response to a PASV command. If libcurl

fails to parse that line, this return code is passed back.

.IP "CURLE_FTP_PRET_FAILED (84)"

The FTP server does not understand the PRET command at all or does not

support the given argument. Be careful when using \fICURLOPT_CUSTOMREQUEST\fP,

a custom LIST command will be sent with PRET CMD before PASV as well.

.IP "CURLE_FTP_CANT_GET_HOST (15)"

An internal failure to lookup the host used for the new connection.

.IP "CURLE_FTP_COULDNT_SET_TYPE (17)"
