   2    xmalloc - a safe malloc
   3
   4    Use this function instead of malloc whenever you don't intend to check
   5    the return value yourself, for instance because you don't have a good
   6    way to handle a zero return value.
   7
   8    Typically, Wine's own memory requests should be handled by this function,
   9    while the clients should use malloc directly (and Wine should return an
  10    error to the client if allocation fails).
