函数名称：audit_alloc_name

函数原型：static struct audit_names *audit_alloc_name(struct audit_context *context, unsigned char type)

返回类型：struct audit_names

参数：

类型参数名称
struct audit_context *context
unsigned chartype
1825  如果文件数小于AUDIT_NAMES is the number of slots we reserve in the audit_context* for saving names from getname(). If we get more names we will allocate* a name dynamically and also add those to the list anchored by names_list. 则
1826  aname等于文件名[文件数]
1827  memset(aname, 0, aname的长度)
1828  否则
1829  aname等于分配内存并置零
1830  如果非aname则返回:NULL
1832  This was an allocated audit_names and not from the array of* names allocated in the task audit context. Thus this name* should be freed on syscall exit. = true
1835  ino等于AUDIT_INO_UNSET
1836  cord type 等于type
1837  添加链表项
1839  文件数自加
1840  返回:aname
