函数名称：字符串转换为整数

函数原型：static int kobject_action_type(const char *buf, size_t count, enum kobject_action *type, const char **args)

返回类型：int

参数：

类型参数名称
const char *buf
size_tcount
enum kobject_action *type
const char **args
69  ret等于负EINVAL
71  如果count且buf[count - 1]恒等于'\n'或buf[count - 1]恒等于'\0'的值则count自减
74  如果非count则转到:out
77  args_start等于在字符串中查找字符
78  如果args_start则
79  count_first等于args_start减buf
80  args_start等于args_start加1
81  否则count_first等于count
84  以action小于ARRAY_SIZE - get the number of elements in array @arr*@arr: array to be sized(he strings here must match the enum in include/linux/kobject.h )循环
85  如果字符串指定长度比较不等于0则继续下一循环
87  如果he strings here must match the enum in include/linux/kobject.h [action][count_first]不等于'\0'则继续下一循环
89  如果args则args等于args_start
91  type等于action
92  ret等于0
93  退出
95  out :
96  返回:ret
