   If I construct a ostrstream, with
     ostrstream os (s,sizeof(s))
   do I have to clean ALL of s before I use it?
   I'm getting strange results (i.e. I have to init ALL of s to 0)
   with g++ 2.7.1, and 2.3.3.

   So, my question is: is this a bug in g++, or am I missing something
   about the string streams?


   The following programme has this what I think is strange behaviour,
   as it outputs in the last line not only the "hello, world", but
   part of the old h's string s was inititalized to,  concatenated to it.

   Thanks for any suggestions.


   #include <iostream.h>
   #include <strstream.h>
   int main(int,char **){
     int i;
     char s[]="\000hhhhhhhhhhhhhhhhhhhhhhhhhhhh";
     cout<<"initial s:"<<s<<endl; //an empty string here.

     ostrstream os(s,sizeof(s));
     os<<"hello, world";
     cout<<s<<endl;          //outputs: hello, worldhhhhhhhhhhhhhhhhh
   }

You've missed to terminate the string. Use 'ends' for an additional
0-char at the end of the string, ie. exchange 'os<<"hello, world";'
by 'os<<"hello, world"<<ends;'.
