The following example shows how xdr_u_char() is used:

#include <stdio.h>
#include <xdr.h>
typedef struct grades
{
        u_char  math; /* Each grade is 'A'..'D' */
        u_char  literature;
         u_char  geography;
        u_char  computers;
} grades ;


bool_t xdr_grades(XDR *xdrs, grades *p_grades)
{
        if(!xdr_u_char(xdrs,&(p_grades->math)))
                return FALSE;
        if(!xdr_u_char(xdrs,&(p_grades->literature)))
                return FALSE;
        if(!xdr_u_char(xdrs,&(p_grades->geography)))
                return FALSE;
        return xdr_u_char(xdrs,&(p_grades->computers));
