内存共享【Delphi版】
一.原理
通过使用“内存映射文件”,实现内存共享
二.主要操作
共享内存结构:
PShareMem = ^TShareMem;
TShareMem = Record
id:string[10];
name:string[20];
age:Integer;
end;
基本变量:
shareMemName:string; //共享内存名
fileHandle : THandle;//内存映射文件句柄
pUserInfoShareMem : PShareMem;//指向共享内存的指针
a)写入程序
1)创建“内存映射文件”
begin
//创建“内存映射文件”
fileHandle:=CreateFileMapping($FFFFFFFF, nil, PAGE_READWRITE, 0, SizeOf(TShareMem), PChar(shareMemName));
if fileHandle <> 0 then
begin
Self.Memo1.Lines.Add('已成功创建内存映射文件!');
end;
end;
2)建立映射关系
//将“内存映射文件”与“应用程序地址空间”建立映射关系
pUserInfoShareMem:=MapViewOfFile(fileHandle,FILE_MAP_ALL_ACCESS,0,0,sizeof(TShareMem));
if pUserInfoShareMem <> nil then
begin
Self.Memo1.Lines.Add('已成功建立映射关系!');
end;
3)写入信息
pUserInfoShareMem.id:='8888';
pUserInfoShareMem.name:='Terry';
pUserInfoShareMem.age:=25;
Self.Memo1.Lines.Add('已向共享内存中写入用户信息!');
4)解除映射关系
//解除“内存映射文件”与“应用程序地址空间”的映射关系
if pUserInfoShareMem<> nil then
UnmapViewOfFile(pUserInfoShareMem);
Self.Memo1.Lines.Add('已成功解除映射关系!');
5)关闭“内存映射文件”
//关闭内存映射文件
if fileHandle<> 0 then
CloseHandle(fileHandle);
Self.Memo1.Lines.Add('已成功关闭内存映射文件!');
b)读取程序
1)打开“内存映射文件”
fileHandle:=OpenFileMapping(FILE_MAP_ALL_ACCESS,false,pchar(shareMemName));
if self.FileHandle <> 0 then
begin
Self.Memo1.Lines.Add('已成功打开内存映射文件!')
end;
2)建立映射关系
pUserInfoShareMem:= MapViewOfFile(self.FileHandle,windows.FILE_MAP_ALL_ACCESS,0,0,sizeof(TShareMem));
if pUserInfoShareMem <> nil then
begin
Self.Memo1.Lines.Add('已成功建立映射关系!');
end;
3)读取信息
if pUserInfoShareMem <> nil then
begin
userInfoStr:='共享内存中获取的用户信息如下:'+#13#10;
userInfoStr:=userInfoStr+'用户Id号:'+pUserInfoShareMem.id+#13#10;
userInfoStr:=userInfoStr+'用户姓名:'+pUserInfoShareMem.name+#13#10;
userInfoStr:=userInfoStr+'用户年龄:'+IntToStr(pUserInfoShareMem.age);
Self.Memo1.Lines.Add(userInfoStr);
end;
4)解除映射关系
if pUserInfoShareMem<> nil then
UnmapViewOfFile(pUserInfoShareMem);
Self.Memo1.Lines.Add('已成功解除映射关系!');
5)关闭“内存映射文件”
if fileHandle<> 0 then
CloseHandle(fileHandle);
Self.Memo1.Lines.Add('已成功关闭内存映射文件!');
c)交互顺序
1)“写入程序”创建共享内存,并写入信息

PS:“写入程序”解除映射关系,关闭内存映射文件对“读取程序”的影响。
1) 写入程序解除映射关系,不影响读取程序的读取操作关闭内存映射文件,会
影响读取程序的读取操作
2) 解除映射关系与关闭内存映射文件无顺序要求,及时不解除映射关系也可直
接关闭内存映射文件
3) 两个程序通讯时,要使用sendmessage,同步操作,而不是postmessage,
防止前者已关闭内存映射文件,而后者还没读取。
三.其他
1)常驻内存参考:建立磁盘物理文件,而不是内存映射文件
