Parameter

Description

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.

UserSuppliedMemory

A pointer to memory for the IO request to be written to, it is up to the caller to make sure that it is large enough. If the pointer is null then the system will allocate memory instead.
