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
