Use
This call implements the same behaviour as Wimp_SlotSize when called with R0 and R1 set to -1. However, the return values are in units of pages instead of bytes. This allows accurate values to be returned on systems with over 2GB of RAM.
Notes
The page size can be read via OS_ReadMemMapInfo.
This call was introduced in Wimp 5.67.
