FSVolume.ReadWriteOperations
Methods implemented for read and write operations that deliver data to and from the extension.
Declaration
protocol ReadWriteOperations : NSObjectProtocolOverview
Most volumes conform to either this protocol or FSVolumeKernelOffloadedIOOperations. You can conform to both if you need to provide kernel-offloaded I/O only for certain files. In that case, files with the inhibitKernelOffloadedIO attribute set use this protocol, and those without it use FSVolumeKernelOffloadedIOOperations. A volume that doesn’t conform to either protocol can’t support any I/O operation.
