Function Documentation

◆ IsWinVer()

bool IsWinVer ( BYTE  vMajor,
BYTE  vMinor,
bool  WinNT = true 
)

IsWinVer returns true if Windows version is greater or equal than argument.
If 'WinNT' is true, caller requires Windows NT, else Windows 9x.

Definition at line 78 of file Common.cpp.

◆ IsWin7()

bool IsWin7 ( )

IsWinVer( 6,1, true );

Definition at line 92 of file Common.cpp.

◆ IsWinVista()

bool IsWinVista ( )

IsWinVer( 6,0, true );

Definition at line 93 of file Common.cpp.

◆ IsWinXP()

bool IsWinXP ( )

IsWinVer( 5,1, true );

Definition at line 94 of file Common.cpp.

◆ IsWin2000()

bool IsWin2000 ( )

IsWinVer( 5,0, true );

Definition at line 95 of file Common.cpp.

◆ IsWinNT()

bool IsWinNT ( )

IsWinVer( 4,0, true );

Definition at line 96 of file Common.cpp.

◆ IsWin98()

bool IsWin98 ( )

IsWinVer( 4,1, false );

Definition at line 97 of file Common.cpp.

◆ IsWin95()

bool IsWin95 ( )

IsWinVer( 4,0, false );

Definition at line 98 of file Common.cpp.

◆ IsWin64Bit()

bool IsWin64Bit ( )

True if running on a Windows x64 version.

Definition at line 100 of file Common.cpp.

◆ IsWow64()

bool IsWow64 ( )

IsWow64 returns true if running under WoW64 (implies proc is 32 bit). See also GetInstanceTargetMachine(), IsWin64Bit()

Definition at line 111 of file Common.cpp.

◆ GetWinSystemInfo()

void GetWinSystemInfo ( SYSTEM_INFO *  si)

GetWinSystemInfo calls either GetSystemInfo() or GetNativeSystemInfo().

Definition at line 135 of file Common.cpp.
