NAME

       SDL::Mixer::Groups - Audio channel group functions

CATEGORY

       Mixer

METHODS

   reserve_channels
	my $reserved = SDL::Mixer::Groups::reserve_channels( $num );

       $num is the number of channels to reserve from default mixing. Zero removes all reservations.

       Reserve $num channels from being used when playing samples when passing in "-1" as a channel number to playback functions.  The channels
       are reserved starting from channel 0 to "$num-1". Passing in zero will unreserve all channels. Normally SDL_mixer starts without any
       channels reserved.

       The following functions are affected by this setting:

       o   SDL::Mixer::Channels::play_channel

       o   SDL::Mixer::Channels::play_channel_timed

       o   SDL::Mixer::Channels::fade_in_channel

       o   SDL::Mixer::Channels::fade_in_channel_timed

       Returns: The number of channels reserved. Never fails, but may return less channels than you ask for, depending on the number of channels
       previously allocated (see SDL::Mixer::Channels::allocate_channels).

   group_channel
	my $grouped = SDL::Mixer::Groups::group_channel( $channel, $group );

       Add a channel to group id (any positive integer), or reset it's group to the default group by passing (-1).

       Returns: True(1) on success. False(0) is returned when the channel specified is invalid.

   group_channels
	my $grouped = SDL::Mixer::Groups::group_channels( $from_channel, $to_channel, $group );

       Add a range of channels to group id (any positive integer), or reset their group to the default group by passing (-1).

       Returns: The number of affected channels.

   group_available
	my $channel = SDL::Mixer::Groups::group_count( $group );

       "group_newer" returns the first available channel of this group.

   group_count
	my $channels = SDL::Mixer::Groups::group_count( $group );

       "group_newer" returns the number of channels in this group.

   group_oldest
	my $channel = SDL::Mixer::Groups::group_oldest( $group );

       "group_newer" returns the channel number which started to play at first.

   group_newer
	my $channel = SDL::Mixer::Groups::group_newer( $group );

       "group_newer" returns the channel number which started to play at last.

   fade_out_group
	SDL::Mixer::Groups::fade_out_group( $group, $ms );

       Fades out the channels by the given group id. The fade-out-time is specified by $ms.

       Returns the number of affected channels.

   halt_group
	SDL::Mixer::Groups::hals_group( $group );

       Halts the channels by the given group id.

       Returns 0.
