Method Detail

globalMemoryStatusEx

public static final MemoryStatusEx globalMemoryStatusEx()
                                                 throws NativeException,
                                                        java.lang.IllegalAccessException

Method globalMemoryStatusEx

 BOOL GlobalMemoryStatusEx(
        LPMEMORYSTATUSEX lpBuffer
 );

         Parameters

         lpBuffer
         [in, out] Pointer to a MEMORYSTATUSEX structure that receives information about current memory availability.

         Return Values

         If the function succeeds, the return value is nonzero.

         If the function fails, the return value is zero. To get extended error information, call GetLastError.
         Remarks

         You can use the GlobalMemoryStatusEx function to determine how much memory your application can allocate without severely impacting other applications.

         The information returned by the GlobalMemoryStatusEx function is volatile. There is no guarantee that two sequential calls to this function will return the same information.
 

Returns:

a MemoryStatusEx

Throws:

NativeException

java.lang.IllegalAccessException
