To create your own allocator, do something like the following:</p> <p>typedef struct _MyAllocator { TidyAllocator base; ...other custom allocator state... } MyAllocator;</p> <p>void* MyAllocator_alloc(TidyAllocator <em>base, void *block, size_t nBytes) { MyAllocator *self = (MyAllocator)base; ... } (etc)</p> <p>static const TidyAllocatorVtbl MyAllocatorVtbl = { MyAllocator_alloc, MyAllocator_realloc, MyAllocator_free, MyAllocator_panic };</p> <p>myAllocator allocator; <a class="el" href="structTidyDoc.html">TidyDoc</a> doc;</p> <p>allocator.base.vtbl = &MyAllocatorVtbl; ...initialise allocator specific state... doc = tidyCreateWithAllocator(&allocator); ...</p> <p>Although this looks slightly long winded, the advantage is that to create a custom allocator you simply need to set the vtbl pointer correctly. The vtbl itself can reside in static/global data, and hence does not need to be initialised each time an allocator is created, and furthermore the memory is shared amongst all created allocators. </p> </div><hr/>The documentation for this struct was generated from the following file:<ul> <li><a class="el" href="tidy_8h_source.html">tidy.h</a></li> </ul> </div><!-- contents --> </div><!-- doc-content --> <!-- start footer part --> <div id="nav-path" class="navpath"><!-- id is needed for treeview function! --> <ul> <li class="navelem"><a class="el" href="struct__TidyAllocator.html">_TidyAllocator</a></li> <li class="footer">Generated on Fri Feb 13 2015 12:51:21 for HTML Tidy by <a href="http://www.doxygen.org/index.html"> <img class="footer" src="doxygen.png" alt="doxygen"/></a> 1.8.9.1 </li> </ul> </div> </body> </html>
