WinBase.MEMORYSTATUSEX (JNA API)

com.sun.jna.platform.win32

## Class WinBase.MEMORYSTATUSEX

- java.lang.Object
- - com.sun.jna.Structure
  - - com.sun.jna.platform.win32.WinBase.MEMORYSTATUSEX

- Enclosing interface:
    WinBase

      public static class WinBase.MEMORYSTATUSEX
      extends Structure

  Contains information about the current state of both physical and virtual memory, including extended memory. The GlobalMemoryStatusEx function stores information in this structure.

    Fields
    Modifier and Type | Field and Description
    --- | ---
    `WinDef.DWORD` | `dwLength` The size of the structure, in bytes.
    `WinDef.DWORD` | `dwMemoryLoad` A number between 0 and 100 that specifies the approximate percentage of physical memory that is in use (0 indicates no memory use and 100 indicates full memory use).
    `WinDef.DWORDLONG` | `ullAvailExtendedVirtual` Reserved.
    `WinDef.DWORDLONG` | `ullAvailPageFile` The maximum amount of memory the current process can commit, in bytes.
    `WinDef.DWORDLONG` | `ullAvailPhys` The amount of physical memory currently available, in bytes.
    `WinDef.DWORDLONG` | `ullAvailVirtual` The amount of unreserved and uncommitted memory currently in the user-mode portion of the virtual address space of the calling process, in bytes.
    `WinDef.DWORDLONG` | `ullTotalPageFile` The current committed memory limit for the system or the current process, whichever is smaller, in bytes.
    `WinDef.DWORDLONG` | `ullTotalPhys` The amount of actual physical memory, in bytes.
    `WinDef.DWORDLONG` | `ullTotalVirtual` The size of the user-mode portion of the virtual address space of the calling process, in bytes.

- - ### Field Detail

    - #### dwLength

          public WinDef.DWORD dwLength

      The size of the structure, in bytes.

    - #### dwMemoryLoad

          public WinDef.DWORD dwMemoryLoad

      A number between 0 and 100 that specifies the approximate percentage of physical memory that is in use (0 indicates no memory use and 100 indicates full memory use).

    - #### ullTotalPhys

          public WinDef.DWORDLONG ullTotalPhys

      The amount of actual physical memory, in bytes.

    - #### ullAvailPhys

          public WinDef.DWORDLONG ullAvailPhys

      The amount of physical memory currently available, in bytes. This is the amount of physical memory that can be immediately reused without having to write its contents to disk first. It is the sum of the size of the standby, free, and zero lists.

    - #### ullTotalPageFile

          public WinDef.DWORDLONG ullTotalPageFile

      The current committed memory limit for the system or the current process, whichever is smaller, in bytes.

    - #### ullAvailPageFile

          public WinDef.DWORDLONG ullAvailPageFile

      The maximum amount of memory the current process can commit, in bytes. This value is equal to or smaller than the system-wide available commit value.

    - #### ullTotalVirtual

          public WinDef.DWORDLONG ullTotalVirtual

      The size of the user-mode portion of the virtual address space of the calling process, in bytes.

    - #### ullAvailVirtual

          public WinDef.DWORDLONG ullAvailVirtual

      The amount of unreserved and uncommitted memory currently in the user-mode portion of the virtual address space of the calling process, in bytes.

    - #### ullAvailExtendedVirtual

          public WinDef.DWORDLONG ullAvailExtendedVirtual

      Reserved. This value is always 0.

  - ### Constructor Detail

    - #### WinBase.MEMORYSTATUSEX

          public WinBase.MEMORYSTATUSEX()

  - ### Method Detail

    - #### getFieldOrder

          protected java.util.List getFieldOrder()

      Description copied from class: `Structure`
      Return this Structure's field names in their proper order. For example,

           protected List getFieldOrder() {
               return Arrays.asList(new String[] { ... });
           }

      IMPORTANT When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g.

           protected List getFieldOrder() {
               List fields = new ArrayList(super.getFieldOrder());
               fields.addAll(Arrays.asList(new String[] { ... }));
               return fields;
           }

      Field order must be explicitly indicated, since the field order as returned by `Class.getFields()` is not guaranteed to be predictable.
      Specified by:
        `getFieldOrder` in class `Structure`
      Returns:
        ordered list of field names
