< 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 >
2012-06-20 07:58:34 +00:00
< 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 > 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 >
