(The fully lock-free implementation uses an AO_t- sized version count, and assumes it does not wrap during the time any given operation is active. This seems reasonably safe on 32-bit hardware, -and very safe on 64-bit hardware.) If a fully lock-free implementation -is used, the macro AO_STACK_IS_LOCK_FREE will be defined. +and very safe on 64-bit hardware.) If a fully lock-free implementation, +AO_stack_is_lock_free() returns 1 (also, the macro AO_STACK_IS_LOCK_FREE is +defined in this case but its usage by client is deprecated). The implementation is interesting only because it allows reuse of existing nodes. This is necessary, for example, to implement a memory |
