我研究了 weak_ptr 。有两种获取原始指针的方法。lock() 功能 shared_ptr<Foo> spFoo = wpPtr.lock(); if(spFoo) { spFoo->DoSomething(); } expired() 功能 if(!wpPtr.expired()) { shared_ptr<Foo> spFoo = wpPtr.lock(); spFoo->DoSomething(); } 哪个是更好的方法?这两种方式有什么不...
while (1) { //遍历睡眠集合,使用resume恢复expired的协程运行权 nty_coroutine *expired = NULL; while ((expired = sleep_tree_expired(sched)) != ) { resume(expired); } //遍历等待集合,使用resume恢复wait的协程运行权 nty_coroutine *wait = NULL; int nready = epoll_wait(sched->epfd, events,...
swap():交换两个智能指针所管理的资源。 expired():检查weak_ptr所指向的资源是否有效,返回true的时候,垃圾回收进程就会清除该指针所指向的内存资源。 use_count():返回智能指针所指向shared_ptr的数量。 lock():获取weak_ptr所指向的shared_ptr实例。 用法说明: weak_ptr不占有内存资源,但是可以指向由shared_ptr...
常见的assert打印和对应信息 WDT timer expired:在ECX00E的log中会出现,说明模组内置看门狗超时。 Memory allocated failed:大部分型号的log中都适配了类似的打印,说明申请内存失败,一般是heap不足或过于碎片化导致。 stack overflow:大部分型号的log中都适配类似打印,说明发生了栈溢出。 illegal poolRef/pMemBlk/pBufHdr...

X系列单板不支持ttl-expired参数。 设备配置的ACL规则应用为软件ACL时才支持vpn-instance和public参数。软件ACL的应用场景请参见《S7700V200R021C10配置指南-安全》ACL配置 -ACL的基本原理中的“ACL的实现方式”。 以上步骤仅是一条permit/deny规则的配置步骤。实际配置ACL规则时,需根据具体的业务需求,决定配置多少条...
