Methods

	Name	Description
	Copy(Byte, Int32, UnmanagedBuffer, Int32, Int32)	Copies data from a managed array to the buffer.
	Copy(UnmanagedBuffer, Int32, Byte, Int32, Int32)	Copies data from a buffer to a managed array.
	CopyCircular(Byte, Int32, UnmanagedBuffer, Int64, Int32)	Copies data from a managed array to the buffer, wrapping around if necessary.
	CopyCircular(UnmanagedBuffer, Int64, Byte, Int32, Int32)	Copies data from a circular buffer to a managed array.
	Dispose	Releases all resources used by this class.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Releases all resources used by this class. (Overrides ObjectFinalize.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)

Remarks

This class is used as an alternative for byte[]. The main differences are that the memory is returned to the OS when the class is disposed/finalized, and the buffer is not zero-initialized.

The main reason for the existence of this class is Mono's reluctance to release memory from the managed heap back to the OS which can lead to pagefile thrashing if you're dealing with many large buffers. This problem may not apply to the sgen garbage collector, but this has not been tested.
