Guardian Procedure Calls Reference Manual

• 4: page size
the page size of physical memory, in bytes.
• 5: memory size
the size of physical memory, in pages. If the number of pages exceeds 2,147,483,647
(2**31 - 1), the returned value is -1D.
• 6: first virtual page
the page number of the first swappable page.
• 7: swappable pages
the current number of memory pages that can be swapped. If the number of pages exceeds
2,147,483,647 (2**31 - 1), the returned value is -1D.
• 8: free pages
the current number of nonallocated memory pages. If the number of pages exceeds
2,147,483,647 (2**31 - 1), the returned value is -1D.
• 9: current locked memory
the current amount of virtual memory, in pages, that is locked in physical memory. If the number
of pages exceeds 2,147,483,647 (2**31 - 1), the returned value is -1D.
• 10: maximum locked memory
the maximum amount of virtual memory, in pages, that can be locked in physical memory. If
the number of pages exceeds 2,147,483,647 (2**31 - 1), the returned value is -1D.
• 11: high locked memory
the maximum amount of virtual memory, in pages, that has been locked in physical memory
at any one time since the processor was loaded. If the number of pages exceeds
2,147,483,647 (2**31 - 1), the returned value is -1D.
• 12: page faults
the number of page-fault interrupts since the processor was loaded. This number is returned
as an unsigned value.
• 13: scans per memory manager call
during a call to the memory manager, the average number of pages, multiplied by 100,
examined before one is found that can be deallocated.
• 14: memory clock cycles
the number of times the memory manager has looked at all swappable pages of memory since
the processor was loaded. This number is returned as an unsigned value.
• 15: memory pressure
an indicator of the frequency of page faults. This number is in the range of 0 (low frequency)
through 7 (high frequency).
• 16: memory queue length
the current number of processes waiting for a page fault to be serviced. The returned value
is an unsigned integer.
• 17: system coldload time
the time (Greenwich mean time, or Coordinated Universal Time) at which the system was cold
loaded.
