Important: The memory for the strings returned by the functions of this DLL are allocated by DLL's heap allocator. When you are done, you must manually dealocate the space allocated for the strings, by calling ReleaseMemory:

 

If you fail to do so, Access Violations may occur. Details.


 

CONSTANTS

FUNCTIONS

 

{ DLL Management }

function GetDllVersion: Real; stdcall;        { Returns the version of this DLL }

 

{ CPU }
function CPUFamily : PAnsiChar; stdcall; { Get cpu identifier from the windows registry }
function GetCPUVendor : PAnsiChar; stdcall; { GetCPUVendor function }
function GetCPUSpeed : Double; stdcall; { The higher the delay, the accurate the result. Default= 200ms }

{ RAM }
function SystemMemStatus (CONST OSMemType : Byte): Cardinal; stdcall; { in Bytes. Limited by the capacity of the OS (32bits OSs will report max 2 or 3 GB). See constants defined above }
function SystemMemStatus_KB (CONST OSMemType : Byte): PAnsiChar; stdcall;
function SystemMemStatus_MB (CONST OSMemType : Byte): PAnsiChar; stdcall;

function ProcessCurrentMem: PAnsiChar; stdcall;

 

{ VIRTUAL RAM }
function GetPageSize : Cardinal; stdcall; { The page size and the granularity of page protection and commitment. This is the page size used by the VirtualAlloc function. }
function GetMemGranularity: Integer; stdcall; { Granularity with which virtual memory is allocated (in KB) }

 

{ RAM - Advanced stuff }

function CoreNumber2CoreMask(CoreNo: integer): integer; stdcall; {Utility function that can be used as 'CPUMask' parameter for 'GetCPUID' }



 


Each exported function is well explained in the source code.

 

 

Explanation for the types used in this DLL:

  • PAnsiChar = null terminated string (equivalent to LPSTR)
  • Byte = 'unsigned char'
  • Cardinal = 32 bits unsigned
  • Integer = 32 bits signed
  • Longint = Same as Integer
  • Byte = 8 bits unsigned
  • Char = Same as Byte
  • More about types here.

 

The following functions are freely accessible (you don't need a to purchase the DLL in order to use them). Note: some functions may be available only in the Delphi version of the DLL.

  • ChangeByteOrder
  • IntToBin
  • CoreNumber2CoreMask
  • WindowsProductID
  • GetPageSize
  • GetMemGranularity
  • GetLowAddr
  • GetHiAddr
  • SystemMemStatus
  • ProcessCurrentMem
  • ProcessPeakMem
  • IsCPUIDAvailable
