## 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.
