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.

Closes #13175

NAME

CURLOPT_FNMATCH_FUNCTION - wildcard match callback

SYNOPSIS

#include <curl/curl.h>

int fnmatch_callback(void *ptr,
                     const char *pattern,
                     const char *string);

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FNMATCH_FUNCTION,
                          fnmatch_callback);

DESCRIPTION

Pass a pointer to your callback function, which should match the prototype shown above.

This callback is used for wildcard matching.

Return CURL_FNMATCHFUNC_MATCH if pattern matches the string, CURL_FNMATCHFUNC_NOMATCH if not or CURL_FNMATCHFUNC_FAIL if an error occurred.

DEFAULT

NULL == an internal function for wildcard matching.

EXAMPLE

extern int string_match(const char *s1, const char *s2);

struct local_stuff {
  void *custom;
};
static int my_fnmatch(void *clientp,
                      const char *pattern, const char *string)
{
  struct local_stuff *data = clientp;
  printf("my pointer: %p\n", data->custom);
  if(string_match(pattern, string))
    return CURL_FNMATCHFUNC_MATCH;
  else
    return CURL_FNMATCHFUNC_NOMATCH;
}

int main(void)
{
  struct local_stuff local_data;
  CURL *curl = curl_easy_init();
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL, "ftp://ftp.example.com/file*");
    curl_easy_setopt(curl, CURLOPT_WILDCARDMATCH, 1L);
    curl_easy_setopt(curl, CURLOPT_FNMATCH_FUNCTION, my_fnmatch);
    curl_easy_setopt(curl, CURLOPT_FNMATCH_DATA, &local_data);
    curl_easy_perform(curl);
  }
}

AVAILABILITY

Added in 7.21.0

RETURN VALUE

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