program.
Public constructors RWpistream(streambuf* s);
Initialize a RWpistream from the streambuf s .
RWpistream(istream& str);
Initialize a RWpistream using the streambuf associated with the istream
str .
Public member functions virtual int get();
Redefined from class RWvistream . Get and return the next character from the
input stream. Returns EOF if end of file is encountered.
virtual RWvistream& get(char& c);
Redefined from class RWvistream . Get the next char and store it in c .
virtual RWvistream& get(wchar_t& wc);
Redefined from class RWvistream . Get the next wide char and store it in wc .
virtual RWvistream& get(unsigned char& c);
Redefined from class RWvistream . Get the next unsigned char and store it in
c .
#include <rw/pstream.h>
main()
{
// Construct a RWpistream to use standard input
RWpistream pstr(cin);
int i;
float f;
double d;
char string[80];
pstr >> i; // Restore an int that was stored in binary
pstr >> f >> d; // Restore a float & double
pstr.getString(string, 80); // Restore a character string
