I usually do:

/* store curl "output" here */
char buffer[BUFFER_SIZE];

/* function that does the copy */
size_t tobuffer(char *ptr, size_t size, size_t nmemb, void *stream)
{
	strncpy(buffer,ptr,size*nmemb);
	return size*nmemb;
}

....
/* tell curl to use the upper function */
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, &tobuffer);
....

then do whatever I want (print, parse, etc) with buffer.
