   SYSTEM_POWER_STATUS_EX status;
   iRet = GetSystemPowerStatusEx (&status, TRUE);

   hb_reta (9);
   hb_stornl ((INT) status.ACLineStatus, -1, 1);
   hb_stornl ((INT) status.BatteryFlag, -1, 2);
   hb_stornl ((INT) status.BatteryLifePercent, -1, 3);
   hb_stornl ((ULONG) status.BatteryLifeTime, -1, 4);
   hb_stornl ((ULONG) status.BatteryFullLifeTime, -1, 5);
   hb_stornl ((INT) status.BackupBatteryFlag, -1, 6);
   hb_stornl ((INT) status.BackupBatteryLifePercent, -1, 7);

   GlobalMemoryStatus (&st);
	
   hb_reta (4);
   hb_stornl ((ULONG) st.dwMemoryLoad, -1, 1);

   hb_stornl ((ULONG) st.dwAvailVirtual, -1, 4);
}
HB_FUNC (DISKINFO)
{
  BOOL iRet;
  unsigned __int64 iFreeBytesToCaller, iTotalBytes, iFreeBytes; 

  iRet = GetDiskFreeSpaceEx(NULL,
  (PULARGE_INTEGER) &iFreeBytesToCaller, 
  (PULARGE_INTEGER) &iTotalBytes, 
  (PULARGE_INTEGER) &iFreeBytes);   
  hb_reta (2);

Hello.

I know nothing about C and I want to use that functions.

With the code you post I did a File util1.c and put there the function posted by Pawelo and the headers posted by Maurizio. Changed the build.bat for compiling... but How do I use them?

Thanks for your help

#pragma BEGINDUMP

#include <hbapi.h>
#include <windows.h>
#include <aygshell.h>

// HB_FUNC (NAME)

Please tell me how do I call that function. I use

And get a linker error
pda.obj : error LNK2001: unresolved external symbol "void __cdecl HB_FUN_BATTERYINFO(void)" (?HB_FUN_BATTERYINFO@@YAXXZ)
pda.exe : fatal error LNK1120: 1 unresolved externals

Jose,

Function BATTERYINFO must be declared with #pragma BEGINDUMP and #pragma ENDDUMP section. Return value is 9-elements array. Function should be include in .prg file.

Code: Select all Collapse
Function Test ()

   Local aBatInfo := BatteryInfo ()

Return .T.

#pragma BEGINDUMP

// #include file

HB_FUNC (BATTERYINFO)
{
   // function body
}

#pragma ENDDUMP


This works.
