[edit] Definition

INT pause_song ( )

Pauses the currently playing song.

[edit] Notes

The song pauses immediately, but can be resumed later by calling resume_song(). For a nicer effect, you may want to fade the music out before pausing. See fade_music_off().

[edit] Returns

INT : Error.

-1 - Error: sound inactive.
0 - No error.
