_TidyAllocator Struct Reference

#include <tidy.h>

Data Fields
const TidyAllocatorVtbl *	vtbl

Detailed Description

An allocator. To create your own allocator, do something like the following:

typedef struct _MyAllocator { TidyAllocator base; ...other custom allocator state... } MyAllocator;

void* MyAllocator_alloc(TidyAllocator <em>base, void *block, size_t nBytes) { MyAllocator *self = (MyAllocator)base; ... } (etc)

static const TidyAllocatorVtbl MyAllocatorVtbl = { MyAllocator_alloc, MyAllocator_realloc, MyAllocator_free, MyAllocator_panic };

myAllocator allocator; TidyDoc doc;

allocator.base.vtbl = &MyAllocatorVtbl; ...initialise allocator specific state... doc = tidyCreateWithAllocator(&allocator); ...

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.
