If you refer to the problem that I am familiar with, by getting rid of the four primitives primitiveFileRead, primitiveFileWrite, primitiveFileGetPosition & primitiveFileSetPosition; replace them with primitiveFileReadFileIDFilePtrIntoArrayStartingAtCount & primitiveFileWriteFileIDFilePtrFromArrayStartingAtCount

That way there is no gap between setting the file position and reading/writing. Some OS's (coughRISC OS) have this as the base api anyway.
