# xdr\_restrict\_buflen(9)

decrease available buffer space

## NAME

xdr\_restrict\_buflen - decrease available buffer space

## SYNOPSIS

**int xdr\_restrict\_buflen(struct xdr\_stream \*** *xdr***, int** *newbuflen***);**

## ARGUMENTS

*xdr*

pointer to xdr\_stream

*newbuflen*

new maximum number of bytes available

## DESCRIPTION

Adjust our idea of how much space is available in the buffer. If we've already used too much space in the buffer, returns -1. If the available space is already smaller than newbuflen, returns 0 and does nothing. Otherwise, adjusts xdr-\>buf-\>buflen to newbuflen and ensures xdr-\>end is set at most offset newbuflen from the start of the buffer.
