The following example shows how xdr_u_long() is used:

#include <stdio.h>
#include <xdr.h>

typedef struct vector
{
        u_long x,y,z;
} vector ;

bool_t xdr_vector(XDR *xdrs, vector *p_vector)
{
        if(!xdr_u_long&((xdrs,p_vector->x)))
                return FALSE;
        if(!xdr_u_long(xdrs,&(p_vector->y)))
                return FALSE;
        return xdr_u_long(xdrs,&(p_vector->z));
}
