PI已替你想好了一个间接办法，你可用一个“共享名”申请一块共享

内存块，进行读写：

HANDLE GetShare(char * &ShareP,int size,char *ShareName)

{ ShareP申请的内存块地址，size字节数，ShareName共享名

HANDLE fh=CreateFileMapping((HANDLE)-1,0,

PAGE_READWRITE,0,

Size,

ShareName);

ShareP=(char *)MapViewOfFile(fh,

FILE_MAP_ALL_ACCESS,

0,0,0);

if (GetLastError()!=ERROR_ALREADY_EXISTS)

ZeroMemory(ShareP,size); // 共享区初始化

return(fh);

}

char * ShareP=NULL;

void test() // 申请一块128个字节的字符数组

{

HANDLE fh=GetShare(ShareP,128,"ShareForMyProg");

for (int i=0;i<128;i++)

ShareP[i]=i;

CloseHandle(fh);

}

HANDLE GetShare(char * &ShareP,int size,char *ShareName)

{ ShareP申请的内存块地址，size字节数，ShareName共享名

HANDLE fh=CreateFileMapping((HANDLE)-1,0,

PAGE_READWRITE,0,

Size,

ShareName);

ShareP=(char *)MapViewOfFile(fh,

FILE_MAP_ALL_ACCESS,

0,0,0);

if (GetLastError()!=ERROR_ALREADY_EXISTS)

ZeroMemory(ShareP,size); // 共享区初始化

return(fh);

}

char * ShareP=NULL;

// 申请一块128个字节的字符数组

HANDLE fh=GetShare(ShareP,128,"ShareForMyProg"); file://申请一块128个字节符数组

for (int i=0;i<128;i++) file://使用、测试

ShareP[i]=i;

.....................

CloseHandle(fh); // 释放共享内存句柄
