NAME

       CURLOPT_FNMATCH_FUNCTION - wildcard matching function 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.

PROTOCOLS

       FTP

EXAMPLE

       static int my_fnmatch(void *clientp,
                             const char *pattern, const char *string)
       {
         struct local_stuff *data = (struct local_stuff *)clientp;
         if(string_match(pattern, string))
           return CURL_FNMATCHFUNC_MATCH;
         else
           return CURL_FNMATCHFUNC_NOMATCH;
       }

       {
         struct local_stuff local_data;
         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);
       }
