* Custom IOCTL call @ 2010-12-10 19:42 Radivoje Jovanovic 2010-12-10 23:23 ` Eliot Blennerhassett 2010-12-13 9:00 ` Clemens Ladisch 0 siblings, 2 replies; 3+ messages in thread From: Radivoje Jovanovic @ 2010-12-10 19:42 UTC (permalink / raw) To: alsa-devel I am writing custom IOCTL calls for my card. I have made hwdep interface and set ioctl ops call for it. But, now the question is which device I need to open in my user space app to talk to correct ioctl? I have tried /dev/snd/controlC0 and /dev/snd/pcmC0D0p Both of theses returned invalid IOCTL. Cheers Ogi ^ permalink raw reply [flat|nested] 3+ messages in thread

"hw:0" ) and snd_hwdep_ioctl(). Regards, Clemens ^ permalink raw reply [flat|nested] 3+ messages in thread
