不阻止,尝试获取 mutex 的所有权。c++ 复制 bool try_lock() _NOEXCEPT; 返回值true,如果方法成功获取 mutex 的所有权,或者调用线程已拥有 mutex;否则,false。备注如果调用线程已拥有 mutex,该函数立即返回 true,并且,以前锁定仍然有效。要求**标头:**mutex...
Final tasks that do the real computational work accumulate partial results in a mutex-protected global variable. This style is only possible with the OpenMP 4.0 taskgroup construct.
