You need to do it to interface to any library written in C (such as
the standard C library for example). For example, try the following
C++ code with and without 'extern "C"'. Without it, you won't be able
to link. Fortunately, all your system headers already provide you with
'extern "C"' by default.
extern "C" void exit(int);
int main()
{
exit(0);
}
