public delegate bool MemoryCleanupCallback(
	ulong requestedByteSize
)

Public Delegate Function MemoryCleanupCallback ( 
	requestedByteSize As ULong
) As Boolean

public delegate bool MemoryCleanupCallback(
	unsigned long long requestedByteSize
)

type MemoryCleanupCallback = 
    delegate of 
        requestedByteSize : uint64 -> bool

Parameters

requestedByteSize

Type: SystemUInt64

Return Value

SoMemoryCleanupCB is called when Open Inventor is not able to allocate at least requestedSize bytes of memory. This notifies the application that available memory is too low. The application can try to release some memory to allow the allocation to succeed. If the callback returns true then Open Inventor will retry its allocation call.
