Retrieve xdr data to decode
__be32 * xdr_inline_decode(struct xdr_stream * xdr, size_t nbytes);
xdr
pointer to xdr_stream struct
nbytes
number of bytes of data to decode
Check if the input buffer is long enough to enable us to decode 'nbytes' more bytes of data starting at the current position. If so return the current pointer, then update the current pointer position.
