xdr_double_char()--Translate between Two-Byte Characters

 #include <rpc/xdr.h>

 bool_t xdr_double_char(XDR *xdrs,
                 char_double_t *cp);

The xdr_double_char() function is a filter primitive that translates between C-language 2-byte characters and their external representation.

Note: Encoded characters are not packed and occupy 2 bytes each. For strings of characters, consider using the xdr_string() API.

Parameters

xdrs  (Input) 

A pointer to the eXternal Data Representation (XDR) stream handle.

cp  (I/O) 

A pointer to the character.

The following example shows how xdr_double_char() is used:

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

typedef struct grades
{
        char_double_t  math; /* Each grade is 'A'..'D' */
        char_double_t  literature;
        char_double_t  geography;
        char_double_t  computers;
} grades ;


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