从C源代码调用C++函数

extern C construct

 // This is C++ code

 // Declare f(int,char,float) using extern "C":
 extern "C" void f(int i, char c, float x);

 ...

 // Define f(int,char,float) in some C++ module:
 void f(int i, char c, float x)
 {
   ...
 }

extern "C"
{
   void func1();
   void func2();
}

extern "C"
{
   void func1()
   {
      /// do something
   }

   void func2()
   {
      // do something else
   }
}

#include extern "C"

   extern "C"
   {
      #include "myHeader.h"
   }
