120 /// \warning This function is not thread-safe. It should not be called at the same time as MemoryMgr::Init or MemoryMgr::Term.
128 /// \warning This function is not thread-safe. It is not valid to allocate memory or otherwise interact with the memory manager during or after this call.
133 /// Performs whatever steps are required to initialize a thread for use with the memory manager.
135 /// The default implementation of the memory manager performs thread initialization automatically and therefore this call is optional.
136 /// For implementations where the cost of automatically initializing a thread for use with an allocator would be prohibitively expensive
137 /// this call allows you to perform the initialization once during, for example, thread creation.
143 /// The default implementation of the memory manager requires that all threads that interact with the memory manager call this function prior
144 /// to either their termination or the termination of the memory manager. Threads not created by the sound engine itself will not have this
146 /// Take care to call this function for any thread, not owned by wwise, that may have interacted with the memory manager. For example job system workers.
153 /// so that any thread-local state can be cleaned up in order to return memory for other systems to use.
154 /// For example, this can be used to return thread-local heaps to global stores or to finalize other deferred operations.
156 /// Therefore, unlike TermForThread, this is not expected to be called in all scenarios by Wwise.
157 /// It is also recommended to be called by game engine integrations in any worker threads that run Wwise jobs.

344 AkUInt32 uMinimumBlockCount; ///< The number of blocks of memory the system is initialized with and is the minimum kept around forever. Defaults to 1. Higher values increase upfront memory use, but can reduce, or eliminate, the creation and destruction of memory blocks over time.
345 AkUInt32 uMinimumBlockSize; ///< The minimum size of each block. If a new allocation requests a new block of memory, then the new block is the size of the requested allocation times four, and then rounded up to the next multiple of this value. Defaults to 2MiB.
346 AkUInt32 uMaximumUnusedBlocks; ///< The maximum number of blocks that the system keeps in an unused state, and avoids freeing. Defaults to 1. Higher values do not increase the peak memory use, but do prevent unused memory from being freed, in order to reduce creation and destruction of memory blocks.
348 // Various debug options for monitoring and analyzing potential issues in usage of the TempAlloc system. All of these are ignored (treated as disabled) in Release configurations.
349 bool bDebugDetailedStats; ///< Enable to track detailed stats and include them in the detailed stat dump. Detailed stats include the size and quantity of each type of allocation from the system. Disabled by default.
350 bool bDebugClearMemory; ///< Enable to clear any allocation to a deterministic garbage value. Useful to make sure memory is initialized properly. Disabled by default.
351 bool bDebugEnableSentinels; ///< Enable to write out sentinels between most allocations to help detect memory overwrites, verified at the end of a tick. Enabled by default. Increases memory usage of blocks slightly.
352 bool bDebugFlushBlocks; ///< Enable to forcefully release all blocks at the end of a tick and recreate them from scratch every tick. Useful to ensure stale memory is not being accessed. Disabled by default. This might interfere with some stats reporting due to blocks being released between ticks.
353 bool bDebugStandaloneAllocs; ///< Enable to force the block size to be as small as possible for each allocation (smaller than can be achieved by just setting uMinimumBlockSize to very low values). Useful to investigate memory overruns in-depth, especially in conjunction with other options like bDebugFlushBlocks and the MemoryMgr's stomp allocator. If enabled, bDebugDetailedStats and bDebugEnableSentinels will be disabled. Greatly increases CPU and memory usage.
362 /// Get a detailed listing of the allocations into the temp-alloc pool, and output them to a file.
