Function projectm_playlist_create 

pub unsafe extern "C" fn projectm_playlist_create(
    projectm_instance: projectm_handle,
) -> projectm_playlist_handle

@brief Creates a playlist manager for the given projectM instance

Only one active playlist manager is supported per projectM instance. If multiple playlists use the same projectM instance, only the last created playlist manager will receive preset change callbacks from the projectM instance.

To switch to another playlist, use the projectm_playlist_connect() method.

@param projectm_instance The projectM instance to connect to. Can be a null pointer to leave the newly created playlist instance unconnected. @return An opaque pointer to the newly created playlist manager instance. Null if creation failed.
