函数名称：xdr_stream_decode_u32 - Decode a 32-bit integer*@xdr: pointer to xdr_stream*@ptr: location to store integer* Return values:* %0 on success* %-EBADMSG on XDR buffer overflow

函数原型：static inline ssize_t xdr_stream_decode_u32(struct xdr_stream *xdr, __u32 *ptr)

返回类型：ssize_t

参数：

类型参数名称
struct xdr_stream *xdr
__u32 *ptr
450  count等于ptr的长度
451  p等于xdr_inline_decode(xdr, count)
453  如果此条件成立可能性小(为编译器优化)(!p)则返回:负EBADMSG
455  ptr等于be32_to_cpup(p)
456  返回:0
