问题 I have an Objective-C app build on Linux with GCC 4.3 using no specific framework (only GNU-runtime). I am using Objective-C exceptions (via the '-fobjc-exceptions' compiler flag). Now I want to print the stack trace of such an exception when I caught some. Or what would make me even happier: put the trace in a string or some kind of structure to evaluate or print it later on. How can that be achieved? 回答1: NSArray * stack = [NSThread callStackSymbols]; It may help. 回答2: Since no more

问题 This is probably a newbie question, but hope you can help me. :) I have something like this: try { //try to do something there } catch (IOException e) { //handle the exception e.printStackTrace(); } I am using NetBeans IDE and for some reason the printStackTrace is underlined in a squiggly line. When I press Alt+Enter, it says Throwable.printStackTrace() should be removed. What does this mean? Could anyone give more insight as what this may mean? Or can I ignore this? Thanks! 回答1: It is just

How to generate javascript stacktrace? [closed]

岁酱吖の 提交于 2019-12-04 04:28:09
Any suggestions on how to, in a cross-browser way, generate a stack trace in javascript? Newer browsers, Chrome and Firefox, expose a console object that allows stack traces to be generated. This method does not provide a method for storing the stack trace to a variable. https://github.com/eriwen/javascript-stacktrace Works quite nicely, but it makes separate ajax requests to load script files included as part of the trace. This seems to be a common method in trace libraries. I'm guessing that browsers do not expose enough information to generate a meaningful stack-trace(line numbers, function

Getting the Stacktrace

我只是一个虾纸丫 提交于 2019-11-28 12:22:49
When Exception happens you can print out the StackTrace and review it. What if you want to get the StackTrace without an exception happening? Is there a way to do this? David Pokluda When you catch an exception you can construct StackTrace object and extract useful information from it. See the following example: StackTrace st = new StackTrace(true); for(int i =0; i< st.FrameCount; i++ ) { // Note that high up the call stack, there is only // one stack frame. StackFrame sf = st.GetFrame(i); Console.WriteLine(); Console.WriteLine("High up the call stack, Method: {0}", sf.GetMethod()); Console
