• 在程序运行时打印相关调用栈信息（函数名，文件行号等）,便于梳理调用逻辑等

//stack.c
#include <stdio.h>
#include <execinfo.h>
#include <stdlib.h>
#include <string.h>
#include <stdbool.h>#define MAX_FRAMES   128
#define BUFFER_SIZE  512// 函数：打印函数调用栈
void PrintStackTrace()
{// 用于存储调用栈帧的地址void *callstack[MAX_FRAMES];// 获取当前调用栈中的函数帧数int frames = backtrace(callstack, MAX_FRAMES);// 如果帧数小于等于0，则表示获取调用栈失败if (frames <= 0){fprintf(stderr, "Failed to retrieve backtrace\n");return;}// 获取调用栈中每个函数对应的符号名char **strs = backtrace_symbols(callstack, frames);if (strs == NULL){fprintf(stderr, "Failed to retrieve backtrace symbols\n");return;}// 打印函数调用栈信息printf("Stack trace:\n");for (int i = 0; i < frames; ++i){// 查找符号名中的地址部分char *address = strchr(strs[i], '[');if (address != NULL){// 将地址部分替换为字符串结束符，以获取纯地址字符串*address = '\0';++address;// 构造命令，使用 addr2line 工具获取地址对应的函数名char command[BUFFER_SIZE];snprintf(command, BUFFER_SIZE, "addr2line -f -e ./stack %s", address);// 执行命令，并读取输出结果FILE *fp = popen(command, "r");if (fp != NULL){char buffer[BUFFER_SIZE];while (fgets(buffer, BUFFER_SIZE, fp) != NULL){// 打印每行输出结果printf("  %s", buffer);}// 关闭命令输出流pclose(fp);}else{// 执行命令失败时输出错误消息fprintf(stderr, "Failed to execute addr2line command\n");}}}// 释放 backtrace_symbols 函数分配的内存free(strs);
}void Bar()
{PrintStackTrace();
}void Foo()
{Bar();
}int main()
{Foo();return 0;
}

• 编译、执行：

gcc -g stack.c -o stack -rdynamic
./stack
