-\section{\module{al} ---

-\modulesynopsis{Audio functions on the SGI.}
-
-
-This module provides access to the audio facilities of the SGI Indy
-and Indigo workstations.  See section 3A of the IRIX man pages for
-details.  You'll need to read those man pages to understand what these
-functions do!  Some of the functions are not available in IRIX
-releases before 4.0.5.  Again, see the manual to check whether a
-specific function is available on your platform.
-
-All functions and methods defined in this module are equivalent to
-the C functions with \samp{AL} prefixed to their name.
-
-Symbolic constants from the C header file \code{<audio.h>} are
-defined in the standard module
-\refmodule[al-constants]{AL}\refstmodindex{AL}, see below.
-
-\warning{The current version of the audio library may dump core
-when bad argument values are passed rather than returning an error
-status.  Unfortunately, since the precise circumstances under which
-this may happen are undocumented and hard to check, the Python
-interface can provide no protection against this kind of problems.
-(One example is specifying an excessive queue size --- there is no
-documented upper limit.)}
-
-The module defines the following functions:
-
-
-\begin{funcdesc}{openport}{name, direction\optional{, config}}
-The name and direction arguments are strings.  The optional
-\var{config} argument is a configuration object as returned by
-\function{newconfig()}.  The return value is an \dfn{audio port
-object}; methods of audio port objects are described below.
-\end{funcdesc}
-
-\begin{funcdesc}{newconfig}{}
-The return value is a new \dfn{audio configuration object}; methods of
-audio configuration objects are described below.
-\end{funcdesc}
-
-\begin{funcdesc}{queryparams}{device}
-The device argument is an integer.  The return value is a list of
-integers containing the data returned by \cfunction{ALqueryparams()}.
-\end{funcdesc}
-
-\begin{funcdesc}{getparams}{device, list}
-The \var{device} argument is an integer.  The list argument is a list
-such as returned by \function{queryparams()}; it is modified in place
-(!).
-\end{funcdesc}
-
-\begin{funcdesc}{setparams}{device, list}
-The \var{device} argument is an integer.  The \var{list} argument is a
-list such as returned by \function{queryparams()}.
-\end{funcdesc}
-
-
-\subsection{Configuration Objects \label{al-config-objects}}
-
-Configuration objects returned by \function{newconfig()} have the
-following methods:
-
-\begin{methoddesc}[audio configuration]{getqueuesize}{}
-Return the queue size.
-\end{methoddesc}
-
-\begin{methoddesc}[audio configuration]{setqueuesize}{size}
-Set the queue size.
-\end{methoddesc}
-
-\begin{methoddesc}[audio configuration]{getwidth}{}
-Get the sample width.
-\end{methoddesc}
-
-\begin{methoddesc}[audio configuration]{setwidth}{width}
-Set the sample width.
-\end{methoddesc}
-
-\begin{methoddesc}[audio configuration]{getchannels}{}
-Get the channel count.
-\end{methoddesc}
-
-\begin{methoddesc}[audio configuration]{setchannels}{nchannels}
-Set the channel count.
-\end{methoddesc}
-
-\begin{methoddesc}[audio configuration]{getsampfmt}{}
-Get the sample format.
-\end{methoddesc}
-
-\begin{methoddesc}[audio configuration]{setsampfmt}{sampfmt}
-Set the sample format.
-\end{methoddesc}
-
-\begin{methoddesc}[audio configuration]{getfloatmax}{}
-Get the maximum value for floating sample formats.
-\end{methoddesc}
-
-\begin{methoddesc}[audio configuration]{setfloatmax}{floatmax}
-Set the maximum value for floating sample formats.
-\end{methoddesc}
-
-
-\subsection{Port Objects \label{al-port-objects}}
-
-Port objects, as returned by \function{openport()}, have the following
-methods:
-
-\begin{methoddesc}[audio port]{closeport}{}
-Close the port.
-\end{methoddesc}
-
-\begin{methoddesc}[audio port]{getfd}{}
-Return the file descriptor as an int.
-\end{methoddesc}
-
-\begin{methoddesc}[audio port]{getfilled}{}
-Return the number of filled samples.
-\end{methoddesc}
-
-\begin{methoddesc}[audio port]{getfillable}{}
-Return the number of fillable samples.
-\end{methoddesc}
-
-\begin{methoddesc}[audio port]{readsamps}{nsamples}
-Read a number of samples from the queue, blocking if necessary.
-Return the data as a string containing the raw data, (e.g., 2 bytes per
-sample in big-endian byte order (high byte, low byte) if you have set
-the sample width to 2 bytes).
-\end{methoddesc}
-
-\begin{methoddesc}[audio port]{writesamps}{samples}
-Write samples into the queue, blocking if necessary.  The samples are
-encoded as described for the \method{readsamps()} return value.
-\end{methoddesc}
-
-\begin{methoddesc}[audio port]{getfillpoint}{}
-Return the `fill point'.
-\end{methoddesc}
-
-\begin{methoddesc}[audio port]{setfillpoint}{fillpoint}
-Set the `fill point'.
-\end{methoddesc}
-
-\begin{methoddesc}[audio port]{getconfig}{}
-Return a configuration object containing the current configuration of
-the port.
-\end{methoddesc}
-
-\begin{methoddesc}[audio port]{setconfig}{config}
-Set the configuration from the argument, a configuration object.
-\end{methoddesc}
-
-\begin{methoddesc}[audio port]{getstatus}{list}
-Get status information on last error.
-\end{methoddesc}

-\section{\module{AL} ---
-         Constants used with the \module{al} module}
-
-\declaremodule[al-constants]{standard}{AL}
-  \platform{IRIX}
-\modulesynopsis{Constants used with the \module{al} module.}
-
-
-This module defines symbolic constants needed to use the built-in
-module \refmodule{al} (see above); they are equivalent to those defined
-in the C header file \code{<audio.h>} except that the name prefix
-\samp{AL_} is omitted.  Read the module source for a complete list of
-the defined names.  Suggested use:
-
-\begin{verbatim}
-import al
-from AL import *
-\end{verbatim}
