Name:unpack_u32

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

Type:bool

Parameter:

TypeParameterName
struct aa_ext *e
unsigned int *data
const char *name
319  pos = pointer to current position in the buffer
321  If 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 Then
322  If Not st if read will be in packed data bounds Then Go to fail
324  If data Then data = le32_to_cpu(get value from possibly mis-aligned location((__le32 * )pointer to current position in the buffer ))
326  pointer to current position in the buffer += sizeof(u32)
327  Return 1
330  fail :
331  pointer to current position in the buffer = pos
332  Return 0
