<p>
</p>
<p>
Prior to 2.10, <a href="glib-Memory-Allocators.html#GAllocator"><span class="type">GAllocator</span></a> was used as an efficient way to allocate
small pieces of memory for use with the <a href="glib-Doubly-Linked-Lists.html#GList"><span class="type">GList</span></a>, <a href="glib-Singly-Linked-Lists.html#GSList"><span class="type">GSList</span></a> and <a href="glib-N-ary-Trees.html#GNode"><span class="type">GNode</span></a> data
structures. Since 2.10, it has been completely replaced by the
<a href="glib-Memory-Slices.html" title="Memory Slices">slice allocator</a> and deprecated.
