void | sf::sleep (Time duration)

## Detailed Description

Base module of SFML, defining various utilities.

It provides vector classes, Unicode strings and conversion functions, threads and mutexes, timing classes.

## Function Documentation

## ◆ getNativeActivity()

ANativeActivity * sf::getNativeActivity | ( |  | ) |

Return a pointer to the Android native activity.

You shouldn't have to use this function, unless you want to implement very specific details, that SFML doesn't support, or to use a workaround for a known issue.

Returns
  Pointer to Android native activity structure

Platform Limitation
  This is only available on Android and to use it, you'll have to specifically include SFML/System/NativeActivity.hpp in your code.

## ◆ sleep()

void sf::sleep | ( | Time | 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
