<div><p>Replacements are provided by a proxy library (release version <samp class="codeph">tbbmalloc_proxy.dll</samp>, debug version <samp class="codeph">tbbmalloc_debug_proxy.dll</samp>). Replacement can be done in one of two ways:</p>
<ul type="disc"><li><p>Add the following header to a source code of any binary which is loaded during application startup.</p>
<pre>#include "tbb/tbbmalloc_proxy.h"</pre></li>
<li><p>Alternatively, add the following parameters to the linker options for the .exe or .dll file that is loaded during application startup. </p>
<p>For 32-bit code (note the triple underscore):</p>
<pre>tbbmalloc_proxy.lib /INCLUDE:"___TBB_malloc_proxy"</pre><p>For 64-bit code (note the double underscore):</p>
<pre>tbbmalloc_proxy.lib /INCLUDE:"__TBB_malloc_proxy"</pre></li>
</ul>
<p>The proxy library implements the following dynamic memory functions:</p>
<ul type="disc"><li><p>Standard C run-time dynamic memory functions: <samp class="codeph">malloc</samp>, <samp class="codeph">calloc</samp>, <samp class="codeph">realloc</samp>, <samp class="codeph">free</samp></p>
</li>
<li><p>Global C++ operators <samp class="codeph">new</samp> and <samp class="codeph">delete</samp>. </p>
</li>
<li><p>Microsoft* C run-time library function <samp class="codeph">_msize</samp></p>
</li>
</ul>
<p>A directory with the proxy library and the appropriate scalable memory allocator library must be available for loading. For example, include the directory in <samp class="codeph">%PATH%</samp>.</p>
