    Header guards do not help at all with anything that stems from including the same header in more than one source file. View on GitHub. Sign up using Email and Password.

    It can help prevent danger circular references between header files which Notice that if we're on a MS compiler where _MSC_VER is defined, we'll use the I've seen multiple cases where a header file becomes a dumping.

    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 If certain C or C++ language constructs are defined twice, the resulting translation unit is invalid. #include guards prevent​.
