it impossible to access blocking mode!
* Rename write() to writeall(), and add a write() method that just
does one write().
* Rearrange/simplify writeall(): in particular, don't supply a timeout
to select(). Let it block forever if it has to.
* Add a bunch of simple ioctl() wrappers: nonblock(), setfmt(),
getfmts(), channels(), speed(), sync(), reset(), post(). These
wrap, respectively, SNDCTL_DSP_NONBLOCK, SNDCTL_DSP_SETFMT,
SNDCTL_DSP_GETFMTS, etc.
* Reduce flush() (which was a wrapper for the SNDCTL_DSP_SYNC ioctl) to
an alias for sync().
* Rearrange the lad_methods list to reflect the order in which the
methods are defined, and add some grouping comments.
This module is a replacement for linuxaudiodev, which will eventually
be deprecated.
Initial revision is rev 2.20 of linuxaudiodev.c, with a rewritten
header comment.
