<h3>
SYNOPSIS</h3>

<br><b>Snack_AddSubCmd</b>(snackCmd, cmdName, cmdProc, delCmdProc)
<h3>

int <b>snackCmd</b> (in)
<br> A flag specifying which command category the new
sub-command belongs to. Valid values are SNACK_SOUND_CMD, SNACK_MIXER_CMD,
or SNACK_AUDIO_CMD.
<p>char <b>*cmdName</b> (in)
<br> Name of the new sub-command.
<p>Snack_CmdProc <b>*cmdProc</b> (in)
<br> Implementation of the new sub-command. cmdProc will
be called whenever cmdName is invoked as a sub-command.
<p>Snack_DelCmdProc <b>*delCmdProc</b> (in)

<h3>
DESCRIPTION</h3>
Snack_AddSubCmd defines a new sub-command for a Snack object command and
associates with it procedure <i>cmdProc</i>, such that whenever <i>cmdName</i>
is invoked as a sub-command (e.g., via a call to Tcl_EvalObj) the Tcl interpreter
will call <i>cmdProc</i> to process the command. New sound sub-commands
must call Snack_GetSound() to determine which sound they invoked on. <i>delCmdProc</i>
is called during clean-up when unloading the extension.
