为什么有时bs_imageIndexContainingAddress会返回UINT_MAX

1

在获取堆栈时，有时会出现bs_imageIndexContainingAddress命中不了image，返回成UINT_MAX，，我把对应的address打印出来，内容的长度为16为，一般业务代码为9位

请问为什么不用系统提供的dladdr方法，而需要自己写一个fl_dladdr呢？

4

系统提供的dladdr方法是线程安全的，而代码中的fl_dladdr其实底层调用的也是系统提供的_dyld_get_image_header和_dyld_get_image_name等方法，而这些方法是线程不安全的，经过我本人的实验对比，fl_dladdr返回的symbolbuffer和dladdr返回的结果是一样的，不清楚作者是出于什么样的考虑自己重写了一个fl_dladdr方法。

大神你好.拜读代码和博客,写的都非常详细,对我帮助很大.十分感谢~ 现在有个小问题:代码173行和179行有两次主线程判断,能否解释一下为什么这样做?是有什么特殊的处理吗? 个人理解第一个主线程判断 return 掉以后,第二个判断应该是走不到的. 望解答~ ```objc if ([nsthread isMainThread]) { return (thread_t)main_thread_id; } for (int i = 0; i < count; ++i) { pthread_t pt = pthread_from_mach_thread_np(list[i]); if ([nsthread...
