filebuf* rdbuf ( ) const; |

Get the associated filebuf object
Returns a pointer to the filebuf object associated with the stream.
Parameters
none
Return Value
A pointer to the
filebuf object associated with the stream.
Notice that for any successfully constructed
ofstream object this pointer is never a null pointer, even if no files have been opened or if the stream is unbuffered.
Example
// copy a file using associated buffer's members
#include <fstream>
using namespace std;
int main () {
char ch;
ifstream infile;
ofstream outfile;
filebuf *inbuf, *outbuf;
infile.open ("test.txt");
outfile.open ("copy.txt");
inbuf=infile.rdbuf();
outbuf=outfile.rdbuf();
ch = inbuf->sgetc();
while ( ch != EOF)
{
outbuf->sputc (ch);
ch= inbuf->snextc();
}
outfile.close();
infile.close();
return 0;
}
