C++ Stream Library

NAME

stdiobuf − iostream specialized to stdio FILE

SYNOPSIS

#include <iostream.h>
#include <stdiostream.h>
#include <stdio.h>
 class stdiobuf : public streambuf {
stdiobuf(FILE* f);
FILE*stdiofile();
};

DESCRIPTION

Operations on a stdiobuf are reflected in the associated FILE.  A stdiobuf is constructed in unbuffered mode, which causes all operations to be reflected immediately in the FILE.  seekg()s and seekp()s are translated into fseek()s.  setbuf() has its usual meaning; if it supplies a reserve area, buffering will be turned back on. 

CAVEATS

stdiobuf is intended to be used when mixing C and C++ code.  New C++ code should prefer to use filebufs, which have better performance.
