The xdr_enum() call translates between C-enumerated groups and their external representations.

Syntax 

#include <rpc\rpc.h>

bool_t
xdr_enum(xdrs, ep)
XDR *xdrs;
enum_t *ep;

Parameters

xdrs

ep

Description

The xdr_enum() call translates between C-enumerated groups and their external representations. When you call the procedures callrpc() and registerrpc(), create a stub procedure for both the server and the client before the procedure of the application program using xdr_enum(). Verify that this procedure looks like the following: 

#include <rpc\rpc.h>
void
static xdr_enum_t(xdrs, ep)
XDR *xdrs;
enum_t *ep;
{
       xdr_enum(xdrs, ep)
}
The xdr_enum_t procedure is used as the inproc and outproc in both the client and server RPCs.

For example, an RPC client would contain the following lines: 

                         ...

error = callrpc(argv[1],ENUMRCVPROG,VERSION,ENUMRCVPROC,
                     xdr_enum_t,&innumber,xdr_enum_t,&outnumber);

                         ...

An RPC server would contain the following line: 

                     
registerrpc(ENUMRCVPROG,VERSION,ENUMRCVPROC,xdr_enum_t,
                    xdr_enum_t);

                         ...

Return Values

The value 1 indicates success; the value 0 indicates an error.
