<h4>Synopsis</h4>
<p>
<pre>
    #include &lt;upc.h&gt;
    shared void *upc_global_alloc(size_t nblocks, 
                                  size_t nbytes);
</pre>
<p>
<h4>Description</h4>

<p>
The <code>upc_global_alloc</code> allocates shared space compatible with the declaration:
<p>
<code>
shared [nbytes] char[nblocks * nbytes]</code>
<p>
<code>upc_global_alloc</code> function is not a collective function. If called by
multiple threads, all threads which make the call get different allocations. If
<code>nblocks*nbytes</code> is zero, the result is a null pointer-to-shared.
