| <div class="textblock"><p>An allocator. 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> |
