NAME¶

xdr_restrict_buflen - decrease available buffer space

SYNOPSIS¶

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

ARGUMENTS¶

xdr

newbuflen

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.
