VC to create DLL dynamic link library method

This article illustrates the method of VC to create DLL dynamic link library. Share with you for your reference. The specific implementation method is as follows:

The header file declares t.h.

#ifdef DLL_API 
#else
#define DLL_API extern "C" _declspec(dllimport)
#endif
DLL_API int a(int cnt);
DLL_API int b(int cnt);

.h file introduction

#define DLL_API extern "C" _declspec(dllexport)
#include "t.h"

Write the body of the function in the CPP file

#define DLL_API extern "C" _declspec(dllexport)
#include "t.h"
int a(int cnt)
{
return cnt+1;
}
int b(int cnt)
{
return cnt+10;
}

Hope that this article described the VC programming for you to help.
