Linux C调用栈打印

#include <execinfo.h>
int backtrace(void **buffer, int size);
char **backtrace_symbols(void *const *buffer, int size);

void print_stack(void)
{
    int size = 128;
    void * array[128];
    int stack_num = backtrace(array, size);
    char ** stacktrace = backtrace_symbols(array, stack_num);
    int i = 0;
    for(i = 0; i < stack_num; i ++) {
        printf("%s %d: %s\n", __func__, __LINE__, stacktrace[i]);
    }

    return ;
}

编译时，添加-rdynamic可显示函数名。

cc -rdynamic prog.c -o prog
