请问 extern "C" 什么意思？

不太明白extern "C" 什么意思，
我知道 extern 变量 什么意思，但这个表示什么呢？

[Cline]

You'll notice the extern "C" modifier. You should use this modifier only if you are writing C++ code, not straight C code. Normally, C++ compilers mangle function and variable names, which can lead to severe linker problems. For example, imagine writing a DLL in C++ and an executable in straight C. When you build the DLL, the function name is mangled, but when you build the executable, the function name is not mangled. When the linker attempts to link the executable, it will complain that the executable refers to a symbol that does not exist. Using extern "C" tells the compiler not to mangle the variable or function names and thereby make the variable or function accessible to executable modules written in C, C++, or any other programming language.
