Include directive. Many programming languages and other computer files have a directive, often called include, import, or copy, that causes the contents of the specified file to be inserted into the original file. These included files are called header files or copybooks. They are often used to define the physical layout of program data, pieces ...
This is a list of file signatures, data used to identify or verify the content of a file. Such signatures are also known as magic numbersor Magic Bytes. Many file formats are not intended to be read as text. If such a file is accidentally viewed as a text file, its contents will be unintelligible. However, some file signatures can be ...
In graphics file formats, the header might give information about an image's size, resolution, number of colors, and the like. In archive file formats, the file header might serve as a fingerprint or signature to identify the specific file format and corresponding software utility.
HTTP. HTTP header fields are a list of strings sent and received by both the client program and server on every HTTP request and response. These headers are usually invisible to the end-user and are only processed or logged by the server and client applications. They define how information sent/received through the connection are encoded (as in ...
An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections.. In computing, the Executable and Linkable Format [2] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, and core dumps.
The application programming interface (API) of the C standard library is declared in a number of header files. Each header file contains one or more function declarations, data type definitions, and macros. After a long period of stability, three new header files (iso646.h, wchar.h, and wctype.h) were added with Normative Addendum 1 (NA1), an ...
include guard. In the C and C++ programming languages, an #include guard, sometimes called a macro guard, header guard or file guard, is a particular construct used to avoid the problem of double inclusion when dealing with the include directive. The C preprocessor processes directives of the form #include <file> in a source file by locating ...
In the C++ programming language, input/output library refers to a family of class templates and supporting functions in the C++ Standard Library that implement stream-based input/output capabilities. [ 1][ 2] It is an object-oriented alternative to C's FILE -based streams from the C standard library. [ 3][ 4]
