<h3>
NAME</h3>
Snack_GetSample, Snack_SetSample - macros to set/get sample values of Snack
sound objects
<h3>
SYNOPSIS</h3>
#include &lt;snack.h>
<br><b>Snack_GetSample</b>(sound, channel, index)
<br><b>Snack_SetSample</b>(sound, channel, index, value)
<h3>
ARGUMENTS</h3>
Sound *sound (in)
<br>&nbsp;&nbsp;&nbsp; A pointer to a sound object to query or modify
<br>int channel (in)
<br>&nbsp;&nbsp;&nbsp; A positive index selecting a channel. 0 = left,
1 = right.
<br>int index (in)
<br>&nbsp;&nbsp;&nbsp; A positive index pointing to a sound sample
<br>float value (in)
<br>&nbsp;&nbsp;&nbsp; The sample value as a float.
<h3>
DESCRIPTION</h3>
The following functions are implemented as macros for performance reasons.
<b>Snack_GetSample</b>
returns the sample value at <i>index</i> of <i>channel</i>.
<b>Snack_SetSample</b>
sets the sample at <i>index</i> of <i>channel</i> to <i>value</i>. No check
is made that
<i>index, channel</i> or <i>value</i> are valid values. These
functions work only with memory resident sounds (SOUND_IN_MEMORY ). Block
transfers can be accomplished more efficiently using the functions Snack_PutSoundData
and Snack_GetSoundData.
