|
/// By default, sf::err() outputs to the same location as std::cerr, |
|
/// (-> the stderr descriptor) which is the console if there's |
|
/// one available. |
|
/// |
|
/// It is a standard std::ostream instance, so it supports all the |
|
/// insertion operations defined by the STL |
|
/// (operator <<, manipulators, etc.). |
|
/// |
|
/// sf::err() can be redirected to write to another output, independantly |
|
/// of std::cerr, by using the rdbuf() function provided by the |
|
/// std::ostream class. |
|
/// |
|
/// Example: |
|
/// \code |
|
/// // Redirect to a file |
|
/// std::ofstream file("sfml-log.txt"); |
|
/// std::streambuf* previous = sf::err().rdbuf(file.rdbuf()); |
|
/// |
|
/// // Redirect to nothing |
|
/// sf::err().rdbuf(NULL); |
|
/// |
|
/// // Restore the original output |
|
/// sf::err().rdbuf(previous); |
|
/// \endcode |
