For #include guards to work properly, each guard must test and conditionally set a different preprocessor macro. Therefore, a project using #include guards must work out a coherent naming scheme for its include guards, and make sure its scheme doesn't conflict with that of any third-party headers it uses, or with the names of any globally visible macros.
Most file systems include attributes of files and directories that control the ability of users to read, change, navigate, and execute the contents of the file system. In some cases, menu options or functions may be made visible or hidden depending on a user's permission level; this kind of user interface is referred to as permission-driven.
File locking is a mechanism that restricts access to a computer file, or to a region of a file, by allowing only one user or process to modify or delete it at a specific time, and preventing reading of the file while it's being modified or deleted.
A debug symbol is a special kind of symbol that attaches additional information to the symbol table of an object file, such as a shared library or an executable.This information allows a symbolic debugger to gain access to information from the source code of the binary, such as the names of identifiers, including variables and routines.
windows.h is a source code header file that Microsoft provides for the development of programs that access the Windows API (WinAPI) via C language syntax. It declares the WinAPI functions, associated data types and common macros. Access to WinAPI can be enabled for a C or C++ program by including it into a source file: #include <windows.h>
The C preprocessor (used with C, C++ and in other contexts) defines an include directive as a line that starts #include and is followed by a file specification. COBOL defines an include directive indicated by copy in order to include a copybook. Generally, for C/C++ the include directive is used to include a header file, but can
Contents Menu allowed users to access folders and files from a context menu without having to open their folders; Desktop Menu allowed users to open items on the desktop from a menu on the Taskbar; Explore From Here enabled users to open Windows Explorer view from any folder such so that the folder acts as the root level folder;
In general, based on a makefile, Make updates target files from source files if any source file has a newer timestamp than the target file or the target file does not exist. For example, this could include compiling C files ( *.c ) into object files , then linking the object files into an executable program.
