							|  |  |  | The \module{winsound} module provides access to the basic | 
					
						
							|  |  |  | sound-playing machinery provided by Windows platforms.  It includes a | 
					
						
							|  |  |  | single function and several constants. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | \begin{funcdesc}{PlaySound}{sound, flags} | 
					
						
							|  |  |  |   Call the underlying \cfunction{PlaySound()} function from the | 
					
						
							|  |  |  |   Platform API.  The \var{sound} parameter may be a filename, audio | 
					
						
							|  |  |  |   data as a string, or \code{None}.  Its interpretation depends on the | 
					
						
							|  |  |  |   value of \var{flags}, which can be a bit-wise ORed combination of | 
					
						
							|  |  |  |   the constants described below.  If the system indicates an error, | 
					
						
							|  |  |  |   \exception{RuntimeError} is raised. | 
					
						
							|  |  |  | \end{funcdesc} | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | \begin{datadesc}{SND_FILENAME} | 
					
						
							|  |  |  |   The \var{sound} parameter is the name of a WAV file. | 
					
						
							|  |  |  | \end{datadesc} | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | \begin{datadesc}{SND_ALIAS} | 
					
						
							|  |  |  |   The \var{sound} parameter should be interpreted as a control panel | 
					
						
							|  |  |  |   sound association name. | 
					
						
							|  |  |  | \end{datadesc} | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | \begin{datadesc}{SND_LOOP} | 
					
						
							|  |  |  |   Play the sound repeatedly.  The \constant{SND_ASYNC} flag must also | 
					
						
							|  |  |  |   be used to avoid blocking. | 
					
						
							|  |  |  | \end{datadesc} | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | \begin{datadesc}{SND_MEMORY} | 
					
						
							|  |  |  |   The \var{sound} parameter to \function{PlaySound()} is a memory | 
					
						
							|  |  |  |   image of a WAV file. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  |   \strong{Note:}  This module does not support playing from a memory | 
					
						
							|  |  |  |   image asynchonously, so a combination of this flag and | 
					
						
							|  |  |  |   \constant{SND_ASYNC} will raise a \exception{RuntimeError}. | 
					
						
							|  |  |  | \end{datadesc} | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | \begin{datadesc}{SND_PURGE} | 
					
						
							|  |  |  |   Stop playing all instances of the specified sound. | 
					
						
							|  |  |  | \end{datadesc} | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | \begin{datadesc}{SND_ASYNC} | 
					
						
							|  |  |  |   Return immediately, allowing sounds to play asynchronously. | 
					
						
							|  |  |  | \end{datadesc} | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | \begin{datadesc}{SND_NODEFAULT} | 
					
						
							|  |  |  |   If the specified sound cannot be found, do not play a default beep. | 
					
						
							|  |  |  | \end{datadesc} | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | \begin{datadesc}{SND_NOSTOP} | 
					
						
							|  |  |  |   Do not interrupt sounds currently playing. | 
					
						
							|  |  |  | \end{datadesc} | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | \begin{datadesc}{SND_NOWAIT} | 
					
						
							|  |  |  |   Return immediately if the sound driver is busy. | 
					
						
							|  |  |  | \end{datadesc} |
