Typedef Documentation

Allocator of fixed size blocks.

Function Documentation

void tommy_allocator_init ( tommy_allocator alloc,
tommy_size_t  block_size,
tommy_size_t  align_size 

Initializes the allocator.

allocAllocator to initialize.
block_sizeSize of the block to allocate.
align_sizeMinimum alignment requirement. No less than sizeof(void*).
void tommy_allocator_done ( tommy_allocator alloc)

Deinitialize the allocator.

It also releases all the allocated memory to the heap.

allocAllocator to deinitialize.
void* tommy_allocator_alloc ( tommy_allocator alloc)

Allocates a block.

allocAllocator to use.
void tommy_allocator_free ( tommy_allocator alloc,
void *  ptr 

Deallocates a block.

You must use the same allocator used in the tommy_allocator_alloc() call.

allocAllocator to use.
ptrBlock to free.
tommy_size_t tommy_allocator_memory_usage ( tommy_allocator alloc)

Gets the size of allocated memory.

allocAllocator to use.
