NAME¶
xdr_restrict_buflen - decrease available buffer space
SYNOPSIS¶
int xdr_restrict_buflen(struct xdr_stream * xdr, int newbuflen);
ARGUMENTS¶
struct xdr_stream * xdr
pointer to xdr_stream
int 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.
