-<p><tt>alloc</tt> metadata may be attached to any instruction returning a
- pointer. It can be used to express the size and offset relative to the
- beginning of the buffer pointed by.</p>
-
-<blockquote>
-
-<p>The first parameter is a function that returns the size of the buffer, and
- the second (optional) parameter is a function that returns the offset from
- the beginning of the buffer. If the second parameter is not present or null,
- the offset is assumed to be null. Both functions must be either readonly or
- readnone.</p>
-<p><tt>alloc</tt> metadata can have additional parameters, which are passed to
- the size and offset functions when they are evaluated. Therefore the size and
- offset functions must have the same signature.</p>

-<div class="doc_code">

- ; size of buffer allocated by this call is my_malloc_size(%s), and offset=0
