Jak uzyskać pamięć szczytową w systemie Mac OS?

Question

W systemie Windows można uzyskać szczytową wykorzystanie pamięci przez wywołanie GetProcessMemoryInfo

function TProcess.Peek: Cardinal; 
var 
    PMC: PPROCESS_MEMORY_COUNTERS; 
    PMCSize: Cardinal; 
begin 
    PMCSize := SizeOf(PROCESS_MEMORY_COUNTERS); 
    GetMem(PMC, PMCSize); 
    try 
    PMC^.cb := PMCSize; 
    if GetProcessMemoryInfo(FHandle, PMC, PMCSize) then 
     Exit(PMC^.PeakWorkingSetSize) 
    else 
     Exit(0); 
    finally 
    FreeMem(PMC); 
    end; 
end;
