但不可能产生死锁,因为std::lock会同时锁定所有互斥锁 std::lock(mtx1, mtx2); // 确保互斥锁在作用域结束时自动释放 std::lock_guard<std::mutex> lock1(mtx1, std::adopt_lock); std::lock_guard
std::vector的优点在于non-sequential access超快,新增数据于数据后端超快,但insert和erase任意资料则相当缓慢;std::list则是insert和erase速度超快,但non-sequential access超慢,此范例以实际时间比较vector和list间的优缺点。 1 /* 2 (C) OOMusou 2006http://oomusou.cnblogs.com 3 4 Filename : VectorVsLis...
