ddebug_iter

函数名称：Advance the iterator to point to the next _ddebug* object from the one the iterator currently points at,* and returns a pointer to the new _ddebug. Returns* NULL if the iterator has seen all the _ddebugs.

函数原型：static struct _ddebug *ddebug_iter_next(struct ddebug_iter *iter)

返回类型：struct _ddebug

参数：

类型	参数	名称
struct ddebug_iter *	iter

748

如果(table == NULL)则返回:NULL

750

如果idx先自加恒等于num_ddebugs则

752

idx等于0

753

如果检查是否为链表尾则

754

table = NULL

755

返回:NULL

757

table等于list_entry - get the struct for this entry*@ptr: the &struct list_head pointer.*@type: the type of the struct this is embedded in.*@member: the name of the list_head within the struct.(链表后项, structddebug_table, link)

760

返回:ddebugs[idx]
