函数名称：pack_nameX - check is the next element is of type X with a name of @name*@e: serialized data extent information (NOT NULL)*@code: type code*@name: name to match to the serialized element

函数原型：static bool unpack_nameX(struct aa_ext *e, enum aa_code code, const char *name)

返回类型：bool

参数：

类型参数名称
struct aa_ext *e
enum aa_codecode
const char *name
274  pos等于pointer to current position in the buffer
279  如果pack control byte 则
280  char * tag = NULL
281  size等于aa_u16_chunck - test and do bounds checking for a u16 size based chunk*@e: serialized data read head (NOT NULL)*@chunk: start address for chunk of data (NOT NULL)* Returns: the size of chunk found with the read head at the end of the chunk.
283  如果name且非size或tag[size - 1]不等于'\0'或字符串比较的值则转到:fail
285  否则如果name则
287  转到:fail
291  如果pack control byte 则返回:1
294  fail :
295  pointer to current position in the buffer 等于pos
296  返回:0
