BackTrace"Use" user-state or kernel-state program to backtrack stack information when exiting abnormally"principle" by analyzing the current stack, backtracking the upper function's frame address in the current stack until the top-level function. A frame address is a memory space in which a local variable, a function return address, and a register value exist in the stack. Because different processor stacks are implemented differently (up and down), t

Glibc provides the backtrace library function to print the call stack. For example, we can register some common signal in the program, such as sigsegment and sigpipe, and then print the call stack using backtrace In the callback functions of these signals, which makes debugging very convenient. Backtrace is easy to use. Use the example code in the man manual. For

BackTrace is an applied self-debugging function introduced by library functions.The three functions in the series can buffer or output a stack frame.#include int backtrace (void **buffer, int size);Char **backtrace_symbols (void *const *buffer, int size);void backtrace_symbols_fd (void *const *buffer, int size, int fd);Transferred from: http://www.linuxidc.com/Linux/2012-11/73470.htmThe usual way to see the

First, Introductionthe BackTrace () series function can be used to output a function call relationship when a code error occurs. A BackTrace is the series of currently active function calls for the program.#include Second, example:#include Operation Result:Mem_err ()Fatal Signaladdr:7 = BackTrace ()callback:./sig_setup () [0x804867b]callback:./sig_setup () [0x804

When you use the gdb debugger, you can view the so-called backtrace, which contains a series of function call Information. You can use the command backtrace or BT to view the information of the function call stack in GDB. In some cases, you can use some related functions in the glibc library function to obtain backtrace information (in the header file execinfo. h

Source: Linux Community AstrotycoonThe usual way to see the function run-time stack is to use an external debugger such as GDB (BT command), but sometimes it is useful to print out the call stack of a function in case of a program error in order to parse the program's bug (mainly for long-running program analysis).In the glibc header file "Execinfo.h", three functions were declared to get the function call stack of the current thread.int BackTrace (vo

There are four ways to get the function call stack for Linux, see called Stack TRACE GENERATION. Here is a brief list of the four scenarios mentioned in this article:Method 1 gcc built-in function __builtin_return_addressMethod 2 BackTrace function in glibcMethod 3 The enhanced BackTrace implemented by Jeff Muizelaar , in addition to the function name, can also get the code line numberMethod 4 LibunwindThi

Generally, you can view the function runtime stack by using an external debugger such as GDB. However, in some cases, to analyze program bugs (mainly for analysis of long-running programs ), it is very useful to print the function call stack when a program error occurs. In the header file "execinfo. H", three functions are declared to obtain the function call stack of the current thread. Function: int backtrace (void ** buffer, intSize) This function

We know that the Android NDK program will generate a tombstone backtrace when it crashes (or take advantage of the ADB Logcat Crawl), and from this backtrace we can see which function caused the crash, but usually because we publish it is Rele ASE version, can not take advantage of the address information in the BackTrace directly to the source code and line numb

The crash log of iOS with the dSYM file can find the backtrace when it crashes, which is the most important information to resolve the crash.If you are packaging on the same Mac, importing crash log will automatically symbolize BackTrace, and you can see the method name, file name, and line numberHowever, sometimes the package is not packaged on your Mac, Xcode can not find the corresponding symbol table,

It seems that many people do not know, so write it. In backtrace, there are generally only some addresses. However, with the addr2line tool, you can find the corresponding code line. The precondition is that the-G option is included when the executable program or dynamic link library is compiled. Specifically, there are two situations: If the backtrace line to be followed is located in an executable file

The source program is as follows: # Include # Include # Include Typedef uint32_t uint32; Void fun3 (void){Void * array [10] = {0 };Uint32 size = 0;Char ** strframe = NULL;Uint32 I = 0, j = 0;Size = backtrace (array, 10 );Strframe = (char **) backtrace_symbols (array, size );Printf ("Print call frame now:/N ");For (I = 0; I Printf ("frame % d -- % s/n", I, strframe [I]);}If (strframe){Free (strframe );Strframe = NULL;}} Void fun2 (void){Fun3 ();} Void

Android under no execinfo.h, you can't print the back trace method under glibc.

The BackTrace function is one of the basic functions of the CallStack debugger, which enables you to see the invocation relationships of functions at all levels. In GdB, this function is called backtrace, and you can enter the BT command to see the callstack of the current function. It's a little bit interesting to realize, and here's a look. Let's look at the basic model of the stack first. Pa
