CURLOPT_PREQUOTE(3)

Library Functions Manual

CURLOPT_PREQUOTE(3)

NAME

CURLOPT_PREQUOTE - commands to run before an FTP transfer

SYNOPSIS

#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

This functionality affects ftp only

EXAMPLE

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

Added in curl 7.9.5

RETURN VALUE

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
