Struct SnapshotDynamicBuffersHelper
Helper class for managing ghost buffers data. Internal use only.
Syntax
public struct SnapshotDynamicBuffersHelper
Methods
CalculateBufferCapacity(UInt32, out UInt32)
Return the history buffer capacity and the resulting size of each history buffer slot necessary to store
the given dynamic data size.

Returns
GetDynamicDataCapacity(UInt32, Int32)
Return the currently available space (masks + buffer data) available in each slot.
Declaration
public static uint GetDynamicDataCapacity(uint headerSize, int length)
Parameters
Returns
GetDynamicDataChangeMaskSize(Int32, Int32)
Compute the size of the bitmask for the given number of elements and mask bits. The size is aligned to 16 bytes.
