XDR_BUF_TRIM(9) 						 Linux Networking						   XDR_BUF_TRIM(9)

NAME
       xdr_buf_trim - lop at most "len" bytes off the end of "buf"

SYNOPSIS
       void xdr_buf_trim(struct xdr_buf * buf, unsigned int len);

ARGUMENTS
       buf
	   buf to be trimmed

       len
	   number of bytes to reduce "buf" by

DESCRIPTION
       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.
