mem_allocator(m_segment->get_segment_manager()好像是分配deque兼容的分配器,不是太懂,有时间看看下面这个例子: #include <boost/interprocess/managed_shared_memory.hpp>#include<boost/interprocess/containers/vector.hpp>#include<boost/interprocess/allocators/allocator.hpp>#include<string>#include<cstdlib>//st...
shared_memory_object 用于创建/打开共享内存对象,需指定名称和访问模式。 #include <boost/interprocess/shared_memory_object.hpp> using namespace boost::interprocess; shared_memory_object shm( open_or_create, // 模式:存在则打开,否则创建 "MySharedMemory", // 唯一标识名称 ...
这样一块内存区用 Boost.Interprocess 的boost::interprocess::shared_memory_object类表示。 为使用这个类,需要包含boost/interprocess/shared_memory_object.hpp头文件。 #include <boost/interprocess/shared_memory_object.hpp> #include <iostream> int main() ...

问boost::interprocess::managed_shared_memory崩溃程序EN本故事纯属虚构。 初入职场的小木，负责维护一个博客系统，后端采用C++编写，部署在Windows服务器上。刚刚熟悉完产品的小木，接到了后台服务的报警，服务器后端偶尔会程序崩溃。刚开始小木还有点慌张，脑子里面浮现出各种问题，这个是程序的bug吗？茫茫的代码如何...
