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.



{ OSMemType used by SystemMemStatus }

MemoryLoad = 1; // Total memory used in percents (%)
TotalPhys = 2; // Total physical memory in bytes
AvailPhys = 3; // Available physical memory (bytes)
TotalPageFile = 4; // Total page file in (bytes)
AvailPageFile = 5; // Available page file (bytes)
TotalVirtual = 6; // Total virtual memory in bytes
AvailVirtual = 7; // Available virtual memory (bytes)


{ ProcMemType used by ProcessMemStatus }

WorkingSetSize =1; //- the current working set size, in bytes.
PageFaultCount =2; //- the number of page faults.
PeakWorkingSetSize =3; //- the peak working set size, in bytes.

function GetCPUCount : Integer; stdcall; { The number of LOGICAL processors in the current group }


{ 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 ProcessMemStatus (CONST ProcMemType: Byte= 1): Cardinal; stdcall; { Returns data about the memory used of the current process }

function ProcessCurrentMem: PAnsiChar; stdcall;


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 GetLowAddr : Cardinal; stdcall; { Lowest RAM memory address accessible to applications (this is the RAM address, not virtual memory address) }

function BiosVideo : PAnsiChar; stdcall;


function GenerateHardwareReport: PAnsiChar; { Before calling this I need to enter a valid key into CubicHardID: }
function FormatBytes (CONST Size: Int64; CONST Decimals: Integer): PAnsiChar; stdcall; { Format bytes to KB, MB, GB, TB }
function BinToInt (Value: PAnsiChar): Integer; stdcall; {Utility. Convers a string representing a binary value '110101010' to integer }
function IntToBin (CONST Value, Digits: integer): PAnsiChar; stdcall; {Utility. Convers an integer to its binary representation such as '110101010' }
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.
