Header files. In computer programming, a header file is a file that allows programmers to separate certain elements of a program's source code into reusable files. Header files commonly contain forward declarations of classes, subroutines, variables, and other identifiers. Programmers who wish to declare standardized identifiers in more than ...
Header (computing) In information technology, header refers to supplemental data placed at the beginning of a block of data being stored or transmitted. In data transmission, the data following the header is sometimes called the payload or body . It is vital that header composition follows a clear and unambiguous specification or format, to ...
Application programming interface (API) Header files. 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.
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.
Precompiled header. In computer programming, a precompiled header (PCH) is a ( C or C++) header file that is compiled into an intermediate form that is faster to process for the compiler. Usage of precompiled headers may significantly reduce compilation time, especially when applied to large header files, header files that include many other ...
The Cache-Control: no-cache HTTP/1.1 header field is also intended for use in requests made by the client. It is a means for the browser to tell the server and any intermediate caches that it wants a fresh version of the resource. The Pragma: no-cache header field, defined in the HTTP/1.0 spec, has the same purpose. It, however, is only defined ...
conio.h is a C header file used mostly by MS-DOS compilers to provide console input/output. It is not part of the C standard library or ISO C, nor is it defined by POSIX.. This header declares several useful library functions for performing "istream input and output" from a program.
Relative offset of local file header (or 0xffffffff for ZIP64). This is the number of bytes between the start of the first disk on which the file occurs, and the start of the local file header. This allows software reading the central directory to locate the position of the file inside the ZIP file. 46: n: File name 46+n: m: Extra field 46+n+m ...
