Syntax

static IBulkDataIORequest * CreateStreamingRequestForRange
(
    const FString & Filename,
    const BulkDataRangeArray & RangeArray,
    EAsyncIOPriorityAndFlags Priority,
    FBulkDataIORequestCallBack * CompleteCallback
)

Remarks

Create an async read request for a range of bulk data streaming tokens The request will read all data between the two given streaming tokens objects. They must both represent areas of data in the file! There is no way to validate this and it is up to the caller to make sure that it is correct. The memory to be read into will be automatically allocated the size of which can be retrieved by calling IBulkDataIORequest::GetSize()

Returns

A request for the read. This is owned by the caller and must be deleted by the caller.

Parameters

Parameter	Description
Filename	The file to read from.
Start	The bulk data to start reading from.
End	The bulk data to finish reading from.
Priority	Priority and flags of the request. If this includes AIOP_FLAG_PRECACHE, then memory will never be returned. The request should always be canceled and waited for, even for a precache request.
CompleteCallback	Called from an arbitrary thread when the request is complete. Can be nullptr, if non-null, must remain valid until it is called. It will always be called.
