The following code excerpt demonstrates the issue:

  char buf[42];
  POSTER_ID p;

  if (posterCreate("foo", sizeof(buf), &p) != OK)
    errx(2, "posterCreate");

  if (posterRead(p, 0, buf, sizeof(buf)) != sizeof(buf))
    errx(2, "posterRead");

  if (posterDelete(p) != OK)
    errx(2, "posterDelete");

The posterRead() will not fail, even though memory has never been initialized.

The attached patch will fix this.
