+  * Beware that this function can fail for several reasons. If the 
+  *  SDL_RWops that feeds the decoder can not seek, this call will almost 
+  *  certainly fail, but this can theoretically be avoided by wrapping it 
+  *  in some sort of buffering SDL_RWops. Some decoders can never seek, 
+  *  others can only seek with certain files. The decoders will set a flag 
+  *  in the sample at creation time to help you determine this.
+  *
+  * You should check sample->flags & SOUND_SAMPLEFLAG_CANSEEK
+  *  before attempting. Sound_Seek() reports failure immediately if this
+  *  flag isn't set. This function can still fail for other reasons if the 
+  *  flag is set.
+  *
+  * This function can be emulated in the application with Sound_Rewind() 
+  *  and predecoding a specific amount of the sample, but this can be 
+  *  extremely inefficient. Sound_Seek() accelerates the seek on a 
+  *  with decoder-specific code.
+  *
+  * If this function fails, the sample should continue to function as if 
+  *  this call was never made. If there was an unrecoverable error,
+  *  sample->flags & SOUND_SAMPLEFLAG_ERROR will be set, which you regular
+  *  decoding loop can pick up.
