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.  

PROTOCOLS

This functionality affects ftp only  

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: %pn", dat->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);
  }
}
