(2)lock和unlock的数量必须相等:看起来std::recursive_mutex很不错,但是使用的时候也需要多注意,否则会出错。 (3)性能的问题,std::recursive_mutex的性能会比较差一些,可用接口auto begin = std::chrono::system_clock::now();测试。 ——> > > std::time_mutex和std::recursive_timed_mutex:这两种互斥量...

当在使用std::chrono库时,出现断言中断的情况,可以尝试以下解决方法:确保使用了正确的头文件:#include <chrono> 检查是否正确使用了std::chrono的命名空间:using namespace std::chrono;确保代码中没有使用了过期或废弃的std::time函数,而是使用了std::chrono库中的高精度时钟函数。以下...

如何序列化std::chrono::system_clock::now()的结果,以便加载它并将其与稍后的时间戳进行比较?我试图以以下方式序列化: std::to_string((uint64_t)std::chrono::system_clock::now().time_since_epoch().count()) 然后,要取消它的序列化: std::chrono::milliseconds t(<uint64 number>); std:...
