创建共享内存: #include <windows.h> #include <iostream> #include <string> #include <cstring> using namespace std; int main() { string strMapName("ShareMemory"); // 内存映射对象名称 string strComData("This is common data!"); // 共享内存中的数据 LPVOID pBuffer; // 共享内存指针 HANDLE...
共享内存块只能通过关联的 SharedMemory 对象引用,因此如果所有的关联到这个共享内存块的 SharedMemory 对象的生命周期都已经结束,那么这个共享内存块的引用计数为 0,于是这个共享内存块也将被回收。 当共享内存块被回收后,我们将无法通过shared_memory.SharedMemory(name="shm_name")来实例化关联到这个共享内存块的 Sh...

生成系统唯一命名的共享内存,在这个例子中使用了SharedMemoryBlock。每次写共享内存的时候都通过Named Mutex对该内存加锁。当写完毕后通过Named Event通知SharedMemoryReader(读共享内存)的进程。 SharedMemoryReader SharedMemoryReader负责读取共享内存的数据。 private voidStartSharedMemoryReading() { MemoryMappedFilemmf =M...

It seems to be caused by using Fast-RTPS shared memory on Windows...we are able to get around some of these issues by doing fastdds.bat shm clean but today we got the error pasted below and aren't sure how to proceed. If anyone has any advice to make this reproducible and/or ...
Internally, a shared section of the pagefile translates into pages of memory that are addressable by more than one process. To do this, Windows NT uses an internal resource called a prototype page-table entry (PPTE). PPTEs enable more than one process to address the same physical page of...
