The library that supports XDR routines must be linked in. The name of this
library is not standard.
Public constructors RWXDRistream(XDR* xp);
Initialize an RWXDRistream from the XDR structure xp.
Public member functions virtual int get();
Redefined from class RWvistream . Gets and return the next character from the
XDR input stream. If the operation fails, it sets the failbit and returns EOF.
virtual RWvistream& get(char& c);
Redefined from class RWvistream . Gets the next character from the XDR input
stream and stores it in c . If the operation fails, it sets the failbit.
virtual RWvistream& get(wchar_t& wc);
Redefined from class RWvistream . Gets the next wide character from the XDR
input stream and stores it in wc . If the operation fails, it sets the failbit.
