                  double *dp);

The xdr_double() function is a filter primitive that translates between C-language double-precision numbers and their external representations.

Parameters

The following example shows how xdr_double() is used:

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

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

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