Constructor

To construct and initialize a filebuf object.

basic_filebuf()

Remarks

The constructor opens a basic_filebuf object and initializes it with basic_streambuf<charT, traits>() and if successful is_open() is false.

Listing: For example of basic_filebuf::basic_filebuf() usage:

// The file ewl-test before operation contains.
// CodeWarrior "Software at Work"

#include <iostream>
#include <fstream> 
#include <cstdio>
#include <cstring>

char inFile[ ] = "ewl-test";

int main()
{ 
using namespace std;
      FILE *fp = fopen( inFile, "a+");
      filebuf   in(fp);

       if( !in.is_open() ) 
           { cout << "could not open file"; exit(1); }

      char str[] = "\n\ttrademark";
      in.sputn(str, strlen(str));

      in.close();
      return 0;   
}

Result:

  The file ewl-test now contains:
