其中的print_stack_trace工作方式类似于callerPerl。 或类似的东西: int main (void){ // will print out debug info every time foo() is called register_stack_trace_function(foo); // etc...} 在哪里register_stack_trace_function放置某种内部断点,这将导致在调用时打印堆栈跟踪foo。 在某些标准C库中是...

Java异常的栈轨迹(Stack Trace) 捕获到异常时,往往需要进行一些处理。比较简单直接的方式就是打印异常栈轨迹Stack Trace。说起栈轨迹,可能很多人和我一样,第一反应就是printStackTrace()方法。其实除了这个方法,还有一些别的内容也是和栈轨迹有关的。
代码例子: #include<stdio.h>#include<stdlib.h>#include<execinfo.h>voidprint_trace(){intMAX_STACK_LEVELS=50;void*buffer[MAX_STACK_LEVELS];intlevels=backtrace(buffer,MAX_STACK_LEVELS);intfd=-1;if(fd!=-1){inti;char**strings=backtrace_symbols(buffer,levels);if(strings!=NULL){for(i=1;i<...
