FS_Entry reason codes:
0 - NoOp - Just return.
1 - Get device name
r0 - 1 (Reason code)
r1 - FS number.
r2 -> Buffer.
r3 -> device name / id.
Exit:
r0 - length of name
r1 - preserved.
r2 - preserved.
r3 - preserved.
2 - Get free space for device.
r0 - 2 (Reason code)
r1 - FS number.
r2 -> Buffer
r3 -> Device name / id .
Exit:

[r2] - Total size of device.
[r2+4] - Free space on device.

The FreeSpace module provides two SWIs:
Free_Register
Entry:
r0 - Filing system number
r1 - Address of routine to call to get free space info (see below)
r1 - r12 on entry to the above routine.
Exit:
Registers preserved.
This must be called in order for the free space module to provide an interactive free space display for a filing system (it is done automatically by the free space module for the following filing systems: ADFS RAMFS NETFS NFS SCSIFS).
Free_Deregister
r0 - Filing system number.
This removes the filing system from the list of known filing systems.
FS_Entry reason codes: (On entry to routine pointed to by r1 in above SWI)
0 - NoOp - Just return.
1 - Get device name
r0 - 1 (Reason code)
r1 - FS number.
r2 -> Buffer.
r3 -> device name / id.

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
