Main predefined values for compilers and windows

The main predefined values of the compiler and Windows operating system affect program compilation. The following is a basic list.

 

(For details about the pre-Definition of C ++ compilation, search "predefined macros" in msdn for a more comprehensive description)

 

I. c ++ pre-defined

_ Cplusplus

It is generally used in the header file of the C library. The method is as follows:

# Ifdef _ cplusplus

Extern "C "{

# Endif

 

... // C library function and data type declaration

 

# Ifdef _ cplusplus

}

# Endif

 

II. C ++ compiler version Definition

The C ++ here refers to the definition of the CL version of The vs (Visual Studio, VC ++) compiler. It can also be said that it is the pre-defined version of vs IDE. (help search, vs2005, vs2008)

Version pre-defined: _ msc_ver

 

Compiler _ msc_ver Value
----------------------
C compiler version 6.0 600
C/C ++ compiler version 7.0 700
Visual c ++, windows, version 1.0 800
Visual c ++, 32-bit, version 1.0 800
Visual c ++, windows, version 2.0 900
Visual c ++, 32-bit, version 2.x 900
Visual c ++, 32-bit, version 4.0 1000
Visual c ++, 32-bit, version 5.0 1100
Visual c ++, 32-bit, version 6.0 1200
Visual c ++, Version 2003. Net 1310

Visual c ++, Version 2005 1400

Visual c ++, version 2008 1500

 

Iii. File compilation options

3.1 pre-defined compilation date:__ Date __

Indicates the compilation date of the current file. The result is a string in the format:Mmm dd yyyy, Where the month nameMmmIn time. hAsctime ()Name of the month in the date generated by the function

Compilation Time:_ Time __

The result is a string in the format:Hh: mm: SS

Last modification time definition:_ Timestamp __

Format:Ddd Mmm date hh: mm: SS yyyy, Where the day is 1 ~ 31

3.2 File Name Pre-definition:_ File __

This file name can be printed at the output position of the file, which is useful in writing exception debugging logs.

File row number pre-defined:_ Line __

The row number of the current Code. It is an integer.

 

Iv. Windows Version Problems

(Note: the translation in this section is based on my understanding of these English terms and may be inaccurate)

There are two methods to define these versions. One is the old predefinition and the other is the new one.

The new predefinition (The following table describes the preferred Macros in use by the Windows header files .):

Minimum system required	Macros to define
Windows Server 2008	Ntddi_version> = ntddi_longhorn
Windows Vista	Ntddi_version> = ntddi_vista
Windows Server 2003 SP1	Ntddi_version> = ntddi_ws03sp1
Windows Server 2003	Ntddi_version> = ntddi_ws03
Windows XP SP2	Ntddi_version> = ntddi_winxpsp2
Windows XP SP1	Ntddi_version> = ntddi_winxpsp1
Windows XP	Ntddi_version> = ntddi_winxp
Windows 2000 SP4	Ntddi_version> = ntddi_win2ksp4
Windows 2000 sp3	Ntddi_version> = ntddi_win2ksp3
Windows 2000 sp2	Ntddi_version> = ntddi_win2ksp2
Windows 2000 sp1	Ntddi_version> = ntddi_win2ksp1
Windows 2000	Ntddi_version> = ntddi_win2k

The following table describes the legacy Macros in use by the Windows header files .):

Windows Vista	_ Win32_winnt> = 0x0600, winver> = 0x0600

Windows XP	_ Win32_winnt> = 0x0501, winver> = 0x0501
Windows 2000	_ Win32_winnt> = 0x0500, winver> = 0x0500
Windows NT 4.0	_ Win32_winnt> = 0x0400, winver> = 0x0400
Windows ME	_ Win32_windows = 0x0500, winver> = 0x0500
Windows 98	_ Win32_windows> = 0x0410, winver> = 0x0410
Windows 95	_ Win32_windows> = 0x0400, winver> = 0x0400

Internet Explorer 6.0 SP1	_ Win32_ie> = 0x0601
Internet Explorer 6.0	_ Win32_ie> = 0x0600
Internet Explorer 5.5	_ Win32_ie> = 0x0550
Internet Explorer 5.01	_ Win32_ie> = 0x0501
Internet Explorer 5.0, 5.0a, 5.0b	_ Win32_ie> = 0x0500
Internet Explorer 4.01	_ Win32_ie> = 0x0401
