c - 使用回调函数报告堆栈回溯

Question

假设我有以下内容:

typedef struct {
   char *name;
   char binding;
   int address;
} Fn_Symbol               //definition of function symbol

static Fn_Symbol *fnSymbols; //array of function symbols in a file
statc int total;  //number of symbol functions in the array and file

static void PrintBacktrace(int sigum, siginfo_t * siginfo, void *context)
{
   printf("\nSignal received %d (%s)\n", signum, strsignal(signum));
   const int eip_index = 14; 
   void *eip = (void *)((struct ucontext *)context)->uc_mcontext.gregs[eip_index];
   printf("Error at [%p]  %s (+0x%x), eip, fnName, offset from start); //?????
   exit(0);
}

到目前为止我已经知道了，但是使用 fnSymbols 静态全局指针来识别发生错误的函数然后通过堆栈回溯以通过地址、名称和偏移量来识别每个调用函数的最佳方法是什么？
