Lop at most len bytes off the end of buf
void xdr_buf_trim(struct xdr_buf * buf, unsigned int len);
buf
buf to be trimmed
len
number of bytes to reduce “buf” by
Trim an xdr_buf by the given number of bytes by fixing up the lengths. Note that it's possible that we'll trim less than that amount if the xdr_buf is too small, or if (for instance) it's all in the head and the parser has already read too far into it.
