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: %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
