.SH NAME
|
||
|
|
CURLOPT_PREQUOTE \- commands to run before an FTP transfer
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PREQUOTE,
|
||
|
|
struct curl_slist *cmds);
|
||
|
|
.fi
|
||
|
|
.SH DESCRIPTION
|
||
|
|
Pass a pointer to a linked list of FTP commands to pass to the server after
|
||
|
|
the transfer type is set. The linked list should be a fully valid list of
|
||
|
|
struct curl_slist structs properly filled in as described for
|
||
|
|
\fICURLOPT_QUOTE(3)\fP.
|
||
|
|
|
||
|
|
Using this option multiple times makes the last set string override the
|
||
|
|
previous ones. Set it to NULL to disable its use again.
|
||
|
|
|
||
|
|
libcurl does not copy the list, it needs to be kept around until after the
|
||
|
|
transfer has completed.
|
||
|
|
|
||
|
|
These commands are not performed when a directory listing is performed, only
|
||
|
|
for file transfers.
|
||
|
|
|
||
|
|
While \fICURLOPT_QUOTE(3)\fP and \fICURLOPT_POSTQUOTE(3)\fP work for SFTP,
|
||
|
|
this option does not.
|
||
|
|
.SH DEFAULT
|
||
|
|
NULL
|
||
|
|
.SH PROTOCOLS
|
||
|
|
This functionality affects ftp only
|
||
|
|
