[英]Print the whole linked list in gdb?
I have a linked list 我有一个链表
struct node {
data_t data;
node_t *next;
};
typedef struct {
node_t *head;
node_t *foot;
node_t *curr; // for iterator
unsigned int size;
} list_t;
with this structure, let say I defined a list 有了这个结构,就说我定义了一个列表
list_t* myList;
How can I use GDB to print the whole linked list? 如何使用GDB打印整个链表?
This should work (but untested): 这应该工作(但未经测试):
define plist
set var $n = $arg0->head
while $n
printf "%d ", $n->data
set var $n = $n->next
end
end
(gdb) plist myList
You could put plist
into ~/.gdbinit
你可以将plist
放入~/.gdbinit
GDB is scriptable in Python. GDB可以用Python编写脚本。 You can define your own pretty-printers and do other useful things. 您可以定义自己的漂亮打印机并执行其他有用的操作。
Better yet, use a standard container, GDB now supports printing those natively. 更好的是,使用标准容器,GDB现在支持本地打印。
