These functions provide memory pool management.
Several mempool are available:
chained_pool:
It is the default one. It allocates a big chunk of memory with malloc() and split the result in chunks of the requested size that are pushed inside a stack. When requested, it takes this pointer from the stack to give them to whoever wants them. pass_through:
it just call malloc() and free(). It may be faster on some computers than using our own allocators (like having a huge L2 cache, over 4MB). one_big:
It call just one time malloc for the requested number of items. Useful when you know in advance how many object of some type will live during the life of the mempool. Eina_Mempool_Repack_Cb |
Type for a callback who need to unreference an old object from a mempool and reference the new one instead.
Memcpy is taken care by the mempool.
