Detailed Description

OS build type name. OS target known at compile time. Actually run environment may vary of course.

The system as a whole. (as far as we can detect) not just the current running app/process or user login. The detected system params may be effected by system virtualization.

Member Function Documentation

◆ get_HeapPtr()

const void* Gray::cSystemInfo::get_HeapPtr ( ) const
inlineoverridevirtualnoexcept

Get the top level (outermost, freeable) class pointer. I can delete get_HeapPtr().

Reimplemented from Gray::cHeapObject.

◆ get_NumberOfProcessors()

UINT Gray::cSystemInfo::get_NumberOfProcessors ( ) const

Is SMP an issue? Do i need to worry about multiple processors ? Creating more worker threads than CPU's might not help you if its a CPU heavy task.

◆ get_OSVer()

UINT Gray::cSystemInfo::get_OSVer ( ) const

from http://msdn.microsoft.com/en-us/library/ms724429(VS.85).aspx

Returns
>= 0x600 = Vista 4.0 = Windows NT 5.0 = Windows 2000 5.1 = Windows XP (Pro or Home) 5.2 = Windows Server 2003 R2 or Home Server or Storage Server 2003 6.0 = Windows Vista or Server 2008 R1 6.1 = Windows 7 or Server 2008 R2 6.2 = Windows 8 or Server 2012

◆ GetSystemDir()

StrLen_t GRAYCALL Gray::cSystemInfo::GetSystemDir ( FILECHAR_t *  pszDir,
StrLen_t  iLenMax 
)
static

Where does the OS keep its files. CSIDL_SYSTEM HRESULT hRes = _FNF(::SHGetFolderPath)( g_MainFrame.GetSafeHwnd(), CSIDL_SYSTEM, nullptr, 0, szPath );

◆ GetSystemName()

HRESULT GRAYCALL Gray::cSystemInfo::GetSystemName ( FILECHAR_t *  pszName,
StrLen_t  iLenMax 
)
static

◆ isOS64Bit()

bool Gray::cSystemInfo::isOS64Bit ( ) const

can both the OS and CPU handle 64 bit apps. A 32 bit app can run on 64 bit system.

◆ SystemBeep()

void GRAYCALL Gray::cSystemInfo::SystemBeep ( )
static

◆ SystemShutdown()

bool GRAYCALL Gray::cSystemInfo::SystemShutdown ( bool  bReboot)
static

Shut down or reboot the whole system. not just log off the user or close the app.
