Jul 03, 2019 1. What is a Header File in C and C? The C/C Standard Library offers its users a variety of functions, one of which is header files. In C, all the header files may or may not end with the.h extension but in C, all the header files must necessarily begin with the.h extension.

Move apps from one mac to another. The header files for the Windows API enable you to create 32- and 64-bit applications. They include declarations for both Unicode and ANSI versions of the API. Mp4 audio editing app for mac. For more information, see Unicode in the Windows API. They use data types that enable you to build both 32- and 64-bit versions of your application from a single source code base. For more information, see Getting Ready for 64-bit Windows. Additional features include Header Annotations and STRICT Type Checking.

Visual C++ and the Windows Header Files

Microsoft Visual C++ includes copies of the Windows header files that were current at the time Visual C++ was released. Therefore, if you install updated header files from an SDK, you may end up with multiple versions of the Windows header files on your computer. If you do not ensure that you are using the latest version of the SDK header files, you will receive the following error code when compiling code that uses features that were introduced after Visual C++ was released: error C2065: undeclared identifier.

Macros for Conditional Declarations

Certain functions that depend on a particular version of Windows are declared using conditional code. This enables you to use the compiler to detect whether your application uses functions that are not supported on its target version(s) of Windows. To compile an application that uses these functions, you must define the appropriate macros. Otherwise, you will receive the C2065 error message.

The Windows header files use macros to indicate which versions of Windows support many programming elements. Therefore, you must define these macros to use new functionality introduced in each major operating system release. (Individual header files may use different macros; therefore, if compilation problems occur, check the header file that contains the definition for conditional definitions.) For more information, see SdkDdkVer.h. Traktor pro 2 2.6 download.

The following table describes the preferred macros used in the Windows header files. If you define NTDDI_VERSION, you must also define _WIN32_WINNT.

Setting WINVER or _WIN32_WINNT

Dev C++ Header Files Youtube

You can define these symbols by using the #define statement in each source file, or by specifying the /D compiler option supported by Visual C++.

For example, to set WINVER in your source file, use the following statement:

#define WINVER 0x0502

#define _WIN32_WINNT 0x0502

To set _WIN32_WINNT using the /D compiler option, use the following command:

cl -c /D_WIN32_WINNT=0x0502source.cpp

For information on using the /D compiler option, see /D (preprocessor definitions).

Header File And C File

Note that some features introduced in the latest version of Windows may be added to a service pack for a previous version of Windows. Therefore, to target a service pack, you may need to define _WIN32_WINNT with the value for the next major operating system release. For example, the GetDllDirectory function was introduced in Windows Server 2003 and is conditionally defined if _WIN32_WINNT is 0x0502 or greater. This function was also added to Windows XP with SP1. Therefore, if you were to define _WIN32_WINNT as 0x0501 to target Windows XP, you would miss features that are defined in Windows XP with SP1.

Controlling Structure Packing

Dev C++ Header Files Download

Projects should be compiled to use the default structure packing, which is currently 8 bytes because the largest integral type is 8 bytes. Doing so ensures that all structure types within the header files are compiled into the application with the same alignment the Windows API expects. It also ensures that structures with 8-byte values are properly aligned and will not cause alignment faults on processors that enforce data alignment.

Faster Builds with Smaller Header Files

You can reduce the size of the Windows header files by excluding some of the less common API declarations as follows:

  • Define WIN32_LEAN_AND_MEAN to exclude APIs such as Cryptography, DDE, RPC, Shell, and Windows Sockets.

    #define WIN32_LEAN_AND_MEAN

  • Define one or more of the NOapi symbols to exclude the API. For example, NOCOMM excludes the serial communication API. For a list of support NOapi symbols, see Windows.h.

    #define NOCOMM
