XDR Array Example 3

Edit online

A party of network users can be implemented as an array in the netuser structure.

The declaration and its associated XDR routines are as follows: 

struct party {
    u_int p_len;
    struct netuser *p_nusers;
};
#define PLEN 500    /*  max number of users in a party  */
bool_t
xdr_party(xdrs, pp)
    XDR *xdrs;
    struct party *pp;
{
    return(xdr_array(xdrs, &pp->p_nusers, &pp->p_len, PLEN,
        sizeof (struct netuser), xdr_netuser));
}
