How do I get WIndows system memory information?

[Vince|Dyalog]

You can use ⎕NA to query the Windows Operating system to get Windows system memory information:

Code: Select all

 r←GlobalMemoryStatusEx;get;rc
⍝ See https://msdn.microsoft.com/en-us/library/windows/desktop/aa366770(v=vs.85).aspx
 'get'⎕NA'U kernel32∣GlobalMemoryStatusEx ={U U {U U} {U U} {U U} {U U} {U U} {U U} {U U}}'
 (rc r)←get⊂64 0,7⍴⊂0 0
 :If rc≠1 ⋄ (⍕rc)⎕SIGNAL 11 ⋄ :EndIf
 (2↓r)←1E¯9×(2*32)⊥∘⌽¨2↓r ⍝ Gigabytes
 r←'Load(%)' 'TotalPhys' 'AvailPhys' 'TotalPageFile' 'AvailPageFile' 'TotalVirtual' 'AvailVirtual',⍪1↓¯1↓r

Example usage and output:

GlobalMemoryStatusEx
Load(%) 72
TotalPhys 16.9696215
AvailPhys 4.730630144
TotalPageFile 25.35632486
AvailPageFile 13.19555891
TotalVirtual 8796.092891
AvailVirtual 8795.017429
