CURLOPT_PREQUOTE explained

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. Disable this operation again by setting a NULL to this option.

While CURLOPT_QUOTE and CURLOPT_POSTQUOTE work for SFTP, this option does not.

DEFAULT

NULL

PROTOCOLS

EXAMPLE

h = curl_slist_append(h, "SYST");

  curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/foo.bin");
 
  /* pass in the FTP commands to run */
  curl_easy_setopt(curl, CURLOPT_PREQUOTE, headerlist);
 
  ret = curl_easy_perform(curl);
 
  curl_easy_cleanup(curl);
}
