    It means do not mangle the symbol name __ImageBase that follows the extern "C". In short it ensures you can use the variable in C++ code.

    extern "C" specify’s the linkage to be applied. In short a Linkage specification.
    It tells the C++ compiler to apply linkage of the type of C to the symbol that follows.
