函数名称：unpack_u32

函数原型：static bool unpack_u32(struct aa_ext *e, unsigned int *data, const char *name)

返回类型：bool

参数：

类型参数名称
struct aa_ext *e
unsigned int *data
const char *name
319  pos等于pointer to current position in the buffer
321  如果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则
322  如果非st if read will be in packed data bounds 则转到:fail
324  如果data则data等于le32_to_cpu(get_unaligned((__le32 * )pointer to current position in the buffer ))
326  pointer to current position in the buffer 加等于sizeof(u32)
327  返回:1
330  fail :
331  pointer to current position in the buffer 等于pos
332  返回:0
