0x01 核心代码

发送端代码：					

					

HANDLE hMapObject;					

HANDLE hMapView;					

					

//创建FileMapping对象					

hMapObject = CreateFileMapping((HANDLE)0xFFFFFFFF,NULL,PAGE_READWRITE,0,0x1000,TEXT("shared"));					

if(!hMapObject)					

{					

	MessageBox(NULL,TEXT("共享内存失败"),TEXT("Error"),MB_OK);				

	return FALSE;				

}					

//将FileMapping对象映射到自己的进程					

hMapView = MapViewOfFile(hMapObject,FILE_MAP_WRITE,0,0,0);					

if(!hMapView)					

{					

	MessageBox(NULL,TEXT("内存映射失败"),TEXT("Error"),MB_OK);				

	return FALSE;				

}					

//向共享内存写入数据					

strcpy((char*)hMapView,"Test Shared Memery");					

					

					

接收端代码：					

					

HANDLE hMapObject;					

HANDLE hMapView;					

					

//创建FileMapping对象					

hMapObject = CreateFileMapping((HANDLE)0xFFFFFFFF,NULL,PAGE_READWRITE,0,0x1000,TEXT("shared"));					

if(!hMapObject)					

{					

	MessageBox(NULL,TEXT("共享内存失败"),TEXT("Error"),MB_OK);				

	return FALSE;				

}					

//将FileMapping对象映射到自己的进程					

hMapView = MapViewOfFile(hMapObject,FILE_MAP_WRITE,0,0,0);					

if(!hMapView)					

{					

	MessageBox(NULL,TEXT("内存映射失败"),TEXT("Error"),MB_OK);				

	return FALSE;				

}					

//从共享内存读取数据					

TCHAR szBuffer[0x1000] = {0};					

memcpy(szBuffer,hMapView,10);

0x03 总结

掌握内存通信的几个函数就好

CreateFileMapping

MapViewOfFile
