libmemcache - custom structures

[Jure Petrovic]

Hello,

Maybe someone already used XDR...
Having 2 structures like this:

bool_t xdr_doubles (XDR *xdrs, doubles *objp)
{
	register int32_t *buf;

	 if (!xdr_double (xdrs, &objp->a))
		 return FALSE;
	 if (!xdr_double (xdrs, &objp->b))
		 return FALSE;
	 if (!xdr_reference (xdrs, (char **)&objp->c, sizeof (person),
(xdrproc_t)xdr_person))
		 return FALSE;
	return TRUE;
} 

bool_t xdr_person (XDR *xdrs, person *objp)
{
	register int32_t *buf;

	 if (!xdr_int (xdrs, &objp->age))
		 return FALSE;
	return TRUE;
}

Now encoding with:

XDR *xdrs = malloc(sizeof(XDR));
char *input = malloc(32);
xdrmem_create(xdrs, input, 32, XDR_ENCODE);
if (xdr_doubles(xdrs, structure)) printf("encode()::success\n");

works great and produces a 16-byte string. But when decoding with:

XDR *xdrs = malloc(sizeof(XDR));
doubles *structure = malloc(sizeof(doubles));
structure->c = NULL; // if null, XDR should allocate memory!!
xdrmem_create(xdrs, input, strlen(input), XDR_DECODE);
if (xdr_doubles(xdrs, structure)) printf("decode()::success\n");

structure->c->age doesn't get filled. As I understand from manuals,
memory for deserializing should get allocated automatically, but it
seems that is not the case.

If I use xdr_pointer() instead of xdr_reference() as suggested, I get a
null pointer for structure->c. 

Any ideas?


Thanks, 
Jure
