NAME

CURLOPT_CHUNK_END_FUNCTION - callback after a transfer with FTP wildcard match

SYNOPSIS

#include <curl/curl.h>
long chunk_end_callback(void *ptr);
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CHUNK_END_FUNCTION,

#include <stdio.h>

data->output = 0x0;
}
return CURL_CHUNK_END_FUNC_OK;
}
int main()
{
/* data for callback */
struct callback_data callback_info;
CURL *curl = curl_easy_init();
curl_easy_setopt(curl, CURLOPT_CHUNK_END_FUNCTION, file_is_downloaded);
