linux--打印函数调用栈

1、示例程序

#include 
#include 
#include 
#include 

int func1()
{
        printf("1234");
        #define SIZE 100
        void *buffer[100];
        int nptrs = backtrace(buffer, SIZE);
        printf("backtrace() returned %d addresses\n", nptrs);
        backtrace_symbols_fd(buffer, nptrs, STDOUT_FILENO);
        return 1;
}

int func2()
{
        func1();
        return 1;
}

int func3()
{
        func2();
        return 1;
}

int main()
{
        func3();
        return 1;
}

2、编译

[root@localhost demo]# gcc -g -rdynamic -o stack stack.c

3、运行

[root@localhost demo]# ./stack

./stack(func2+0xe)[0x4011cd]
./stack(func3+0xe)[0x4011e2]
./stack(main+0xe)[0x4011f7]
