Availability: IRIX.
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 "AL" prefixed to their name.
Symbolic constants from the C header file <audio.h> are
defined in the standard module
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:
| openport( |
name, direction[, config]) |
-
The name and direction arguments are strings. The optional
config argument is a configuration object as returned by
newconfig(). The return value is an audio port
object; methods of audio port objects are described below.
-
The return value is a new audio configuration object; methods of
audio configuration objects are described below.
-
The device argument is an integer. The return value is a list of
integers containing the data returned by ALqueryparams().
-
The device argument is an integer. The list argument is a list
such as returned by queryparams(); it is modified in place
(!).
-
The device argument is an integer. The list argument is a
list such as returned by queryparams().
Release 2.5.2, documentation updated on 21th February, 2008.
