 <a name="glib-Memory-Chunks.description"></a><h2>Description</h2>
 <p>
 Memory chunks provide an space-efficient way to allocate equal-sized
 pieces of memory, called atoms. However, due to the administrative
 overhead (in particular for <a class="link" href="glib-Memory-Chunks.html#G-ALLOC-AND-FREE:CAPS" title="G_ALLOC_AND_FREE"><span class="type">G_ALLOC_AND_FREE</span></a>, and when used from
 multiple threads), they are in practise often slower than direct use
 of <a class="link" href="glib-Memory-Allocation.html#g-malloc" title="g_malloc ()"><code class="function">g_malloc()</code></a>. Therefore, memory chunks have been deprecated in
 favor of the <a class="link" href="glib-Memory-Slices.html" title="Memory Slices">slice
 allocator</a>, which has been added in 2.10. All internal uses of
 memory chunks in GLib have been converted to the
 <code class="literal">g_slice</code> API.
 </p>
 <p>
 There are two types of memory chunks, <a class="link" href="glib-Memory-Chunks.html#G-ALLOC-ONLY:CAPS" title="G_ALLOC_ONLY"><span class="type">G_ALLOC_ONLY</span></a>, and
 <a class="link" href="glib-Memory-Chunks.html#G-ALLOC-AND-FREE:CAPS" title="G_ALLOC_AND_FREE"><span class="type">G_ALLOC_AND_FREE</span></a>. </p>
 <div class="itemizedlist"><ul class="itemizedlist" type="disc">
 <li class="listitem"><p> <a class="link" href="glib-Memory-Chunks.html#G-ALLOC-ONLY:CAPS" title="G_ALLOC_ONLY"><span class="type">G_ALLOC_ONLY</span></a>
 chunks only allow allocation of atoms. The atoms can never be freed
 individually. The memory chunk can only be free in its entirety.
 </p></li>
 <li class="listitem"><p> <a class="link" href="glib-Memory-Chunks.html#G-ALLOC-AND-FREE:CAPS" title="G_ALLOC_AND_FREE"><span class="type">G_ALLOC_AND_FREE</span></a> chunks do
 allow atoms to be freed individually. The disadvantage of this is
 that the memory chunk has to keep track of which atoms have been
 freed. This results in more memory being used and a slight
 degradation in performance. </p></li>
 </ul></div>
 <p>
 </p>
 <p>
 To create a memory chunk use <a class="link" href="glib-Memory-Chunks.html#g-mem-chunk-new" title="g_mem_chunk_new ()"><code class="function">g_mem_chunk_new()</code></a> or the convenience
 macro <a class="link" href="glib-Memory-Chunks.html#g-mem-chunk-create" title="g_mem_chunk_create()"><code class="function">g_mem_chunk_create()</code></a>.
 </p>
 <p>
 To allocate a new atom use <a class="link" href="glib-Memory-Chunks.html#g-mem-chunk-alloc" title="g_mem_chunk_alloc ()"><code class="function">g_mem_chunk_alloc()</code></a>,
 <a class="link" href="glib-Memory-Chunks.html#g-mem-chunk-alloc0" title="g_mem_chunk_alloc0 ()"><code class="function">g_mem_chunk_alloc0()</code></a>, or the convenience macros <a class="link" href="glib-Memory-Chunks.html#g-chunk-new" title="g_chunk_new()"><code class="function">g_chunk_new()</code></a> or
 <a class="link" href="glib-Memory-Chunks.html#g-chunk-new0" title="g_chunk_new0()"><code class="function">g_chunk_new0()</code></a>.
 </p>
 <p>
 To free an atom use <a class="link" href="glib-Memory-Chunks.html#g-mem-chunk-free" title="g_mem_chunk_free ()"><code class="function">g_mem_chunk_free()</code></a>, or the convenience macro
 <a class="link" href="glib-Memory-Chunks.html#g-chunk-free" title="g_chunk_free()"><code class="function">g_chunk_free()</code></a>. (Atoms can only be freed if the memory chunk is
 created with the type set to <a class="link" href="glib-Memory-Chunks.html#G-ALLOC-AND-FREE:CAPS" title="G_ALLOC_AND_FREE"><span class="type">G_ALLOC_AND_FREE</span></a>.)
 </p>
 <p>
 To free any blocks of memory which are no longer being used, use
 <a class="link" href="glib-Memory-Chunks.html#g-mem-chunk-clean" title="g_mem_chunk_clean ()"><code class="function">g_mem_chunk_clean()</code></a>. To clean all memory chunks, use <a class="link" href="glib-Memory-Chunks.html#g-blow-chunks" title="g_blow_chunks ()"><code class="function">g_blow_chunks()</code></a>.
 </p>
 <p>
 To reset the memory chunk, freeing all of the atoms, use
 <a class="link" href="glib-Memory-Chunks.html#g-mem-chunk-reset" title="g_mem_chunk_reset ()"><code class="function">g_mem_chunk_reset()</code></a>.
 </p>
 <p>
 To destroy a memory chunk, use <a class="link" href="glib-Memory-Chunks.html#g-mem-chunk-destroy" title="g_mem_chunk_destroy ()"><code class="function">g_mem_chunk_destroy()</code></a>.
 </p>
 <p>
 To help debug memory chunks, use <a class="link" href="glib-Memory-Chunks.html#g-mem-chunk-info" title="g_mem_chunk_info ()"><code class="function">g_mem_chunk_info()</code></a> and
 <a class="link" href="glib-Memory-Chunks.html#g-mem-chunk-print" title="g_mem_chunk_print ()"><code class="function">g_mem_chunk_print()</code></a>.
