Use
The purpose of this call is to return any additional features of FileCore to a client filing system prior to it registering.
Notes
This call is only of use to filing systems which register as a FileCore filing system to allow it to select different code paths where necessary to communicate with older versions of FileCore.
With old versions of FileCore this will be an unknown SWI, but each new feature flag is defined to be set so:
SWI "XFileCore_Features" MOVVS R0, #0; no new features at all
This call is only available from RISC OS 5.00 onwards.
