1. boost::interprocess::managed_shared_memory to support managed shared memory. This class lets you instantiate objects that have their memory located in shared memory, making the objects automatically available to any program that accesses the same shared memory. #include <boost/interprocess/managed_...
to allocate portions of a fixed size memory segment). Using these mechanisms,Boost.Interprocessoffers useful tools to construct C++ objects, including STL-like containers, in shared memory and memory mapped files:(与此同时,BI也提供了
当遇到 boost::interprocess::shared_memory no such file or directory 错误时,通常意味着编译器无法找到 Boost.Interprocess 库中的 shared_memory 相关的头文件或库文件。以下是几个可能的解决步骤: 确认Boost 库已正确安装: 确保你已经从 Boost 官方网站或其他可靠来源下载了 Boost 库,并且已经按照官方文档或相关...
Boost.Interprocessallows creating complex objects in shared memory and memory mapped files. For example, we can construct STL-like containers in shared memory. To do this, we just need to create a special (managed) shared memory segment, declare aBoost.Interprocessallocator and construct the vector...
Boost.Interprocess翻译-快速入门 You can just allocate a portion of a shared memory segment, copy the message to that buffer, send the offset of that portion of shared memory to another process, and you are done. Let's see the example:...
LSM,全称为Lightweight Shared Memory Communications and Marshalling,也即是一个轻量级的共享内存通信库,为了解决大规模数据在几个进程节点间交换的效率问题而提出的。 有别于一般的跨进程使用UDP或TCP方式,LSM直接将数据存放在一段共享内存处,其他接收方仅需要直接从该段内存读取即可。 目前LSM通过Boost.Interprocess实...

boost::interprocess::shared_memory_object::truncate shared_memory的truncate作用是什么? 注释:Sets the size of the shared memory mapping. 1.当一个共享内存对象被创建了,它的大小是0。为了设置共享内存的大小,使用者需在一个已经以读写方式打开的共享内存中调用truncate 函数:shm_obj.truncate(10000);...
