[Cbe-oss-dev] libspe: errno handling

[Jeremy Kerr]

Hi libspe-ers,

We have a whole heap of this sort of construct in libspe:

	priv->fd_spe_dir = spu_create(/* args omitted */);

	if (priv->fd_spe_dir < 0) {
		/* error handling code omitted*/
		errno = EFAULT;
		return NULL;
	}

ie, we overwrite the kernel's errno with something else.

Is there a reason for this? generally, leaving errno as-is will give 
users a much better idea of what went wrong.

Cheers,


Jeremy
