Function Documentation

sf::Err

(

)

Standard stream used by SFML to output warnings and errors.

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:

 // 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);

void SFML_API sf::Sleep

(

Uint32

duration

)

Make the current thread sleep for a given duration.

sf::Sleep is the best way to block a program or one of its threads, as it doesn't consume any CPU power.

Parameters:

duration

Time to sleep, in milliseconds
