boost的named_mutex的一些坑 最近遇到一个问题,程序在a用户下运行后,然后注销windows,登陆b用户,发现程序奔溃,抓了下堆栈,发现了boost的named_mutex一些细节,记录下 1 2 3 #include <boost/interprocess/sync/named_mutex.hpp> #include <boost/interprocess/creation_tags.hpp> boost::interprocess::named_mutex mu...
使用头文件相对位置为:boost/interprocess/sync/named_mutex.hpp 在程序中使用 boost::interprocess::named_mutex g_namedmutex(boost::interprocess::open_or_create, "theMutexName"); boost::interprocess::scoped_lock<boost::interprocess::named_mutex> lock(g_namedmutex);...

STL中boost interprocess的named_mutex相当于什么 空无一人。 您必须下拉至特定于平台的 API

Semaphores (named and anonymous) Upgradable mutexes File locks Mutex 互斥锁(Mutex)代表着互斥,它是进程之间同步的最基本形式。互斥锁保证只有一个线程可以锁定给定的互斥锁。如果一段代码被互斥锁的锁定和解锁所包围,那么就可以保证一次只有一个线程执行该段代码。当该线程解锁互斥锁时,其他线程可以进入该代码区域:...
interprocess; int main() { managed_shared_memory managed_shm{open_or_create, "shm", 1024}; int *i = managed_shm.find_or_construct<int>("Integer")(); named_mutex named_mtx{open_or_create, "mtx"}; named_mtx.lock(); ++(*i); std::cout << *i << '\n'; named_mtx.unlock();...
