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.
