What does it mean? Will an STL implementation have an internal cache to reuse the memory for old string streams and other types? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. The copy of the underlying string returned by str is a temporary object that will be destructed at the end of the expression, so directly calling c_str() on the result of str() (for example in auto *ptr = out.str().c_str();) results in a dangling pointer. It essentially wraps a raw array I/O device implementation (std::strstreambuf) into the higher-level interface of std::basic_ostream.The typical implementation of ostrstream holds only one non-derived data member: an object of type std::strstreambuf. 2) Uses a copy of str as initial contents of the underlying string device. One of the oversights is that there is no non-copying access to the internal buffer of a basic_stringbuf which makes at least the obtaining Before any call to str() that uses the result as a C string, the buffer must be null-terminated, typically with std::ends. This means that any attempts to modify the end of the stream require copying the underlying buffer or reading bytes until the end. The underlying basic_stringbuf object is constructed as basic_stringbuf(str, mode | ios_base::out). This operator (<<) applied to an output stream is known as insertion operator.It is overloaded as a member function for: (1) arithmetic types Generates a sequence of characters with the representation of val, properly formatted according to the locale and other formatting settings selected in the stream, and inserts them into the output stream. specifies stream open mode.
