name: duk_alloc_raw

proto: |
  void *duk_alloc_raw(duk_context *ctx, duk_size_t size);

summary: |
  <p>Allocate <code>size</code> bytes using the raw allocation function registered
  to the context.  If allocation fails, returns <code>NULL</code>.  If <code>size</code>
  is zero, the call may either return a <code>NULL</code> or some non-<code>NULL</code>
  value which may be safely given to e.g. <code>duk_free_raw()</code>.  The allocation
  cannot trigger a garbage collection, and the allocated memory is not automatically
  garbage collected.  The allocated memory is not automatically zeroed, and may contain
  arbitrary garbage.</p>

  <p>Memory allocated with <code>duk_alloc_raw()</code> can be freed with either
  <code><a href="#duk_free">duk_free()</a></code> or
  <code><a href="#duk_free_raw">duk_free_raw()</a></code>.</p>

example: |
  void *buf = duk_alloc_raw(ctx, 1024);
  if (buf) {
      printf("allocation successful: %p\n", buf);
  } else {
      printf("allocation failed\n");
  }
