Use
This call can be used to enumerate the data items which are present in the “extended ROM footer” which is present in most modern versions of RISC OS 5.
Notes
The contents of the ROM footer is generally only of interest to low-level system components. No guarantees are made as to what tags will be available on any given system. To allow for the possibility of tag IDs or tag content to be changed in future versions of the OS, the use of this SWI by user software is discouraged.
This call was introduced in RISC OS 5.23.
