# xdr\_set\_scratch\_buffer(9)

Attach a scratch buffer for decoding data.

## NAME

xdr\_set\_scratch\_buffer - Attach a scratch buffer for decoding data.

## SYNOPSIS

**void xdr\_set\_scratch\_buffer(struct xdr\_stream \*** *xdr***, void \*** *buf***, size\_t** *buflen***);**

## ARGUMENTS

*xdr*

pointer to xdr\_stream struct

*buf*

pointer to an empty buffer

*buflen*

size of 'buf'

## DESCRIPTION

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.
