[slang-users] intrinsic curl_easy_escape sample

["Brian McQueen" <mcqueenorama@xxxxxxxxx>]

Here is an attempt with a known problem.  curl_easy_escape actually
mallocs for its returned string, which means this thing has a memory
leak.  I figure that means I need to turn it into a memory managed
thing.  What do you think of this?

Also I don't know what the hashed strings are.  Could you say a word
about those?

Here is the sample:


static void escape_intrin (void)
{
  SLang_MMT_Type *mmt;
  Easy_Type *ez;
  char *unescaped_string = NULL;
  char *esc_string = NULL;

  if (-1 == SLpop_string (&unescaped_string))
       return;

  if (NULL == (mmt = pop_easy_type (&ez, 0)))
    return;

  esc_string = curl_easy_escape(ez->handle, unescaped_string, 0);

  if (esc_string == NULL)
       return;

  (void) SLang_push_string (esc_string);

  SLfree(unescaped_string);
  SLang_free_mmt (mmt);
}
