Hi,

I am in need of transferring a file to a server using http post. Being new to both http programming and libcurl is a deadly combination I guess. from the sample code available on the libcurl site here I was able to write this code.

#include <stdio.h>
#include <fcntl.h>
#include <sys/stat.h>
#include <curl/curl.h>

size_t read_callback(void *ptr, size_t size, size_t nmemb, void *stream)
{
   size_t retcode;

   retcode = fread(ptr, size, nmemb, stream);

   fprintf(stderr, "*** We read %d bytes from file\n", retcode);

   return retcode;
}

int main(int argc, char **argv)
{
   CURL *curl;
   CURLcode res;
   FILE * hd_src ;
   int hd ;
   struct stat file_info;
   char *file;
   char *url;

   if(argc < 3)
   return 1;

   file= argv[1];
   url = argv[2];
   hd = open(file, O_RDONLY) ;
   fstat(hd, &file_info);
   close(hd) ;

   hd_src = fopen(file, "rb");

   curl_global_init(CURL_GLOBAL_ALL);

   curl = curl_easy_init();
   if(curl) {
   // curl_easy_setopt(curl, CURLOPT_READFUNCTION, read_callback);
   // curl_easy_setopt(curl, CURLOPT_UPLOAD, 1);
      curl_easy_setopt(curl, CURLOPT_POST, 1);
      curl_easy_setopt(curl, CURLOPT_URL, url);
      curl_easy_setopt(curl, CURLOPT_READDATA, hd_src);
      curl_easy_setopt(curl, CURLOPT_INFILESIZE,(curl_off_t)file_info.st_size);
      printf("size:%d\n",file_info.st_size);

      res = curl_easy_perform(curl);
      printf("%d\n",res);
      curl_easy_cleanup(curl);
   }
   fclose(hd_src);
   curl_global_cleanup();
   return 0;
}

Ethereal packet analysis shows content-length to be zero. Can some one help me out?

Thanks for your time:)
