Use the HEADERDATA for the headerfunction:

#include <curl/curl.h>

size_t my_headers(char *data,
                  size_t size, size_t nitems,
                  void *myowncrap)
{
  fprintf(stderr, "Got %d bytes: %s", size * nitems, myowncrap);
  return size * nitems;
}

int main(void)
{
  CURL *curl;
  curl = curl_easy_init ();
  curl_easy_setopt (curl, CURLOPT_URL, "http://daniel.haxx.se/");
  curl_easy_setopt (curl, CURLOPT_HEADERDATA, "I am here where are you?\n");
  curl_easy_setopt (curl, CURLOPT_HEADERFUNCTION, my_headers);
  curl_easy_perform (curl);
  curl_easy_cleanup(curl);
  return 0;
}
