Use
The purpose of this call is to read or set the amount of memory allocated to the current, or next application to be loaded.
Notes
None. The use of 32bit integers means that the returned values may be incorrect on systems with over 2GB ofRAM (especially the free pool size). To avoid this, consider using Wimp_Extend (read slot size), which will return the values in units of pages.
