Sample - DDLs in C++: Implicit Linking                                             Notes   Code

Simple DLL that Prints a Text:

#include "iostream.h"  //cout

BOOL APIENTRY DllMain( HANDLE hModule, 
                       DWORD  ul_reason_for_call, 
                       LPVOID lpReserved)
{
    return TRUE;
}

__declspec(dllexport) void WriteString()
{
    cout << "This string printed from DLL ..." << endl;
};

Calling DLL in Console Application:

#include <windows.h>  //for HINSTANCE
#include "iostream.h"

/******************************************************************************
* Use of __declspec(dllimport) is optional, but it improves efficiency of the *
*                              code.                                           *
*******************************************************************************/

/*__declspec(dllimport)*/ void WriteString();

void main()
{
    WriteString();
}

Console Output:

This string printed from DLL ...
