Attach a scratch buffer for decoding data.
void xdr_set_scratch_buffer(struct xdr_stream * xdr, void * buf, size_t buflen);
xdr
pointer to xdr_stream struct
buf
pointer to an empty buffer
buflen
size of 'buf'
The scratch buffer is used when decoding from an array of pages. If an xdr_inline_decode call spans across page boundaries, then we copy the data into the scratch buffer in order to allow linear access.
