# NAME
CURLOPT_PREQUOTE - commands to run before an FTP transfer
# SYNOPSIS
~~~c
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PREQUOTE,
struct curl_slist *cmds);
~~~
# 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
CURLOPT_QUOTE(3). Disable this operation again by setting a NULL to this
option.
These commands are not performed when a directory listing is performed, only
for file transfers.
While CURLOPT_QUOTE(3) and CURLOPT_POSTQUOTE(3) work for SFTP,
this option does not.
# DEFAULT
NULL
# PROTOCOLS
FTP
# EXAMPLE
~~~c
int main(void)
{
struct curl_slist *cmdlist = NULL;
cmdlist = curl_slist_append(cmdlist, "SYST");
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/foo.bin");
/* pass in the FTP commands to run */
curl_easy_setopt(curl, CURLOPT_PREQUOTE, cmdlist);
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
~~~
# AVAILABILITY
Along with the protocol support
# RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
