docs/libcurl: generate PROTOCOLS from meta-data
Remove the PROTOCOLS section from the source files completely and
instead generate them based on the header data in the curldown files.

It also generates TLS backend information for options marked for TLS as
protocol.

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

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

Along with the protocol support

RETURN VALUE

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