Set subbuf to a portion of buf
int xdr_buf_subsegment(struct xdr_buf * buf, struct xdr_buf * subbuf, unsigned int base, unsigned int len);
buf
an xdr buffer
subbuf
the result buffer
base
beginning of range in bytes
len
length of range in bytes
sets subbuf to an xdr buffer representing the portion of buf of length len starting at offset base.
buf and subbuf may be pointers to the same struct xdr_buf.
Returns -1 if base of length are out of bounds.
