C++11 introduces the to_string overloads, but only for native numeric types (int, long, double, float and their unsigned counterparts). But for a lot of types, stringification abilities are implemented by overloading operator<< to send data over to a stream: std::ostream& operator<<(std::ostream& os, MyType const& myObject);
This function is used internally for saving environments. Parameters: out : The ostream to which to write. s : The string to write. Mar 18, 2008 Like istream and ostream, the string streams provide a buffer to hold data.

Looks like it was already reported to libc++ almost a year ago: Bug 41563 - operator<<(ostream, string) declared in but defined in . I've bumped the thread. UPD: actually, there is no mention whether this is a libc++ bug or feature. 👍

This doesn't answer the question, which was "convert ostream to std:string" – Danny Mar 18 '17 at 6:57. 7. Weird. From what I see, neither the title nor text of the question contain the word "ostringstream", while your answer does not contain the word "ostream".
A raw_ostream that writes to an std::string.. This is a simple adaptor class.

To get cout to accept a Date object after the insertion operator, overload the insertion operator to recognize an ostream object on the left and a Date on the right. The overloaded << operator function must then be declared as a friend of class Date so it can access the private data within a Date object.
This is Jun 10, 2006 The console internally stores a std::stringstream which gives it's streambuf to other input/output streams so that they write to it. Now, since I Apr 24, 2017 Therefore, it happens very often that a memory allocation kicks in when you deal with C and C++ strings.
