The C++ language has an active proposal for transactional memory. It can be enabled in GCC 6 and newer when compiling with -fgnu-tm. [8] [73] Unicode identifiers Although the C++ language requires support for non-ASCII Unicode characters in identifiers, the feature has only been supported since GCC 10.
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.

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
For example, Windows installers for gedit, GIMP, and HexChat all include identical copies of the GTK toolkit, which these programs use to render widgets. On the other hand, if different versions of GTK are required by each application, then this is the correct behavior and successfully avoids dependency hell.
Several macros affect the definitions made by windows.h and the files it includes. UNICODE – when defined, this causes the generic text datatype TCHAR to be a synonym of WCHAR instead of CHAR, and all type-generic API functions and messages that work with text will be defined to the -W versions instead of the -A versions.
Common exceptions include an invalid argument (e.g. value is outside of the domain of a function), [5] an unavailable resource (like a missing file, [6] a network drive error, [7] or out-of-memory errors [8]), or that the routine has detected a normal condition that requires special handling, e.g., attention, end of file.
