使用 gdb 进行调试时，如何打印整个链接结构列表中的所有特定属性？

Question

Supposing a linked-list have lots of nodes, and each node is a struct like this

struct sth{
    int key;
    struct sth * next;
};

How could I print all the "key" values in gdb easily instead of input commands like print (*head).key , print (*head->next).key , print (*head->next->next).key ...

thx.

You can write a custom pretty-printer in Python and plug it into gdb 7.0 or later. Here's a good-looking tutorial: http://blog.rethinkdb.com/make-debugging-easier-with-custom-pretty-prin
