函数原型：int ima_alloc_init_template(struct ima_event_data *event_data, struct ima_template_entry **entry, struct ima_template_desc *desc)

返回类型：int

参数：

类型参数名称
struct ima_event_data *event_data
struct ima_template_entry **entry
struct ima_template_desc *desc
41  result等于0
43  如果desc则template_desc等于desc
45  否则template_desc等于ima_template_desc_current()
48  entry等于分配内存并置零
50  如果非entry则返回:负ENOMEM
53  template descriptor 等于template_desc
54  以i小于num_fields循环
55  field等于fields[i]
59  result等于field_init(event_data, & ( template related data [i]))
61  如果result不等于0则转到:out
64  len等于len
65  template_data_len加等于len的长度
66  template_data_len加等于len
68  返回:0
69  out :
70  ma_free_template_entry - free an existing template entry
71  * entry = NULL
72  返回:result
