I'm trying to set up nonblocking writes to /dev/audio from within perl.
It won't let me:
$ cat ft.pl
#!/usr/bin/perl
use warnings;
use strict;
use Fcntl;
my $fh_out;
my $outfile="/dev/audio";
my $flags;
open($fh_out, ">", $outfile) or die("open $outfile: $!");
$flags=fcntl($fh_out, F_GETFL, 0) or die("fcntl GET $outfile: $!");
$flags=fcntl($fh_out, F_SETFL, $flags | O_NONBLOCK) or die("fcntl SET $outfile:
$!");
$ ./ft.pl
fcntl SET /dev/audio: Inappropriate ioctl for device at ./ft.pl line 13.
$
Am I doing something silly here? Or is there a bug?
I see the same result on i386 and amd64. Same for /dev/sound.
This works on a 5.5 release, but not on later releases or current.
Incidentally, are there perl bindings for the native sound interface
sio_open(3)?
