Fields

pIOMemory: *mut c_void

Pointer for I/O memory allocated by user. Pass NULL if you want memory to be allocated via AK::MemoryMgr::Malign(). If specified, uIOMemorySize, uIOMemoryAlignment and ePoolAttributes are ignored.

uIOMemorySize: AkUInt32

Size of memory for I/O (for automatic streams). It is passed directly to AK::MemoryMgr::Malign(), after having been rounded down to a multiple of uGranularity.

uIOMemoryAlignment: AkUInt32

I/O memory alignment. It is passed directly to AK::MemoryMgr::Malign().

ePoolAttributes: AkUInt32

Attributes for I/O memory. Here, specify the allocation type (AkMemType_Device, and so on). It is passed directly to AK::MemoryMgr::Malign().

uGranularity: AkUInt32

I/O requests granularity (typical bytes/request).

uSchedulerTypeFlags: AkUInt32

Scheduler type flags.

threadProperties: AkThreadProperties

Scheduler thread properties.

fTargetAutoStmBufferLength: AkReal32

Targetted automatic stream buffer length (ms). When a stream reaches that buffering, it stops being scheduled for I/O except if the scheduler is idle.

uMaxConcurrentIO: AkUInt32

Maximum number of transfers that can be sent simultaneously to the Low-Level I/O (applies to AK_SCHEDULER_DEFERRED_LINED_UP device only).

bUseStreamCache: bool

If true the device attempts to reuse IO buffers that have already been streamed from disk. This is particularly useful when streaming small looping sounds. The drawback is a small CPU hit when allocating memory, and a slightly larger memory footprint in the StreamManager pool.

uMaxCachePinnedBytes: AkUInt32

Maximum number of bytes that can be “pinned” using AK::SoundEngine::PinEventInStreamCache() or AK::IAkStreamMgr::PinFileInCache()
