Porting an OSS application

[Riccardo Mottola <riccardo.mottola%libero.it@localhost>]

Hi,

I am trying to port the gnustep audio player to NetBSD with its OSS 
backend. It is known to work on OpenBSD and on Linux using oss. I am on 
NetBSD 6.99

When I compile it, I get:
OSS.m: In function '-[OSS _setRateAndChannels]':
OSS.m:111:37: error: macro "ioctl" requires 3 arguments, but only 2 given
OSS.m:111:39: warning: comparison between pointer and integer
gmake[4]: *** [obj/OSS.obj/OSS.m.o] Error 1

the offending line is:

if (ioctl (dspFd, SNDCTL_DSP_RESET) == -1)

Why the error? the argument number is variadic and it compiles on the 
abovementioned platforms (as well as FreeBSD and others). It is such 
also in the examples you find aorund on the net.

Somebody writes it that way:
ioctl (dspFd, SNDCTL_DSP_RESET, 0)

This way it compiles on NetBSD. i wonder though if it is correct and 
work and if it affect other platforms.

It compies then, but when running it will say:

2012-05-02 12:33:22.237 Cynthiune[19288] error preparing output for 1 
channels at a rate of 22050

And no sound :(
