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);
