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.
