CURLOPT_PREQUOTE

[Bylon2]

I did this

Copie/Paste the example...

I expected the following

I expect the example to work... it does not!

In fact there is a typo (same one in POSTQUOTE and QUOTE)

struct curl_slist *h = NULL;
h = curl_slist_append(h, "SYST");
 
curl = curl_easy_init();
if(curl) {
  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);
}

$ gcc -Wall -std=c11 example.c -o example $(curl-config --cflags --libs)
example.c: In function ‘main’:

In file included from /usr/include/curl/curl.h:2402:0,
                 from example.c:3:
example.c:39:49: error: ‘headerlist’ undeclared (first use in this function)
  res = curl_easy_setopt(curl, CURLOPT_PREQUOTE, headerlist);

The curl_easy_setopt call should be instead:
curl_easy_setopt(curl, CURLOPT_PREQUOTE, h);

Alternatively, the example could start with:

struct curl_slist *headerlist = NULL;
headerlist = curl_slist_append(headerlist, "SYST");

... which is probably a better option because 'headerlist' is a more self descriptive variable than 'h':

Thanks. I renamed it to cmdlist since it's not a headerlist.

Excellent, thanks!
