str

To return the character array stored in the buffer.

char* str();

The function str() freezes the buffer and appends a null character then returns the beginning pointer for the input sequence. The user is responsible for destruction of any dynamically allocated buffer.

#include <iostream>
#include <strstream>

const int size = 100;
char buf[size];
char arr[size] = "CodeWarrior - Software at Work";   

int main()
{    
   ostrstream ostr(buf, size);
   ostr << arr;

       // associate buffer
   strstreambuf *strbuf(ostr.rdbuf());   

       // do some manipulations
   strbuf->pubseekoff(10,ios::beg); 
   strbuf->sputc('\0');
   strbuf->pubseekoff(0, ios::beg);

   cout << "The original array was\n" << arr << "\n\n";
   cout << "The strstreambuf array is\n" 
      << strbuf->str() << "\n\n";
   cout << "The ostrstream array is now\n" << buf;
   return 0;
}
