xdr_netobj()--Translate between Netobj Structures and Their XDR

 #include <rpc/xdr.h>

 bool_t xdr_netobj(XDR *xdrs,
                   struct netobj *np);

The xdr_netobj() function is a filter primitive that translates between variable-length opaque data and its external representation.

Parameters

xdrs  (Input) 

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

np  (I/O) 

A pointer to the address of the netobj structure that contains both a length and a pointer to the opaque data.

Authorities

No authorization is required.

Return Value

Error Conditions

None.

The following example shows how xdr_netobj() is used:

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

/*
 * Handle of an external client -
 * pid - process ID of the server process on our host
 * oid - object ID of the server assigned to that client
 * Typical case when the other side needs a handle, without
 * actually knowing what is it. We can use xdr_netobj() to send
 * the value
 * or xdr_opaque() to send a pointer.

{
        int pid;
        int oid;
