udfGetPwrCapabilities

 Keywords: System S4 GetPwrCapabilities Hibernate Hibernation Power DllCall PowrProf.dll

Question:

How can I check if hibernation has been enabled/configured on a system.I'm seeking information for both XP and Win7.

Answer:

#DefineFunction udfGetPwrCapabilities()
   structcnt = 29
   structsize =  139
   arrSystemPowerCapabilities = ArrDimension(structcnt)
   dllfilename = DirWindows(1):'PowrProf.dll'
   lpSystemPowerCapabilities = BinaryAlloc(structsize)
   BinaryEodSet( lpSystemPowerCapabilities, structsize )
   retval = DllCall( dllfilename, long:"GetPwrCapabilities", lpbinary:lpSystemPowerCapabilities)
   If retval == 0
      Pause('GetPwrCapabilities Failed',DllLastError())
      BinaryFree(lpSystemPowerCapabilities)
      Return 0
   EndIf
   BinaryEodSet( lpSystemPowerCapabilities, BinaryEodGet(lpSystemPowerCapabilities) )
