NAME

6       xdr_restrict_buflen - decrease available buffer space
7

SYNOPSIS

9       int xdr_restrict_buflen(struct xdr_stream * xdr, int newbuflen);
10

ARGUMENTS

12       xdr
13           pointer to xdr_stream
14
15       newbuflen
16           new maximum number of bytes available
17

DESCRIPTION

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