The timer id is specified in t= he following strcuture: struct snd_timer_select { struct snd_timer_id id; /* timer ID */ unsigned char reserved[32]; /* reserved */ }; A pointer to this structure should be passed as the third ioctl's argum= ent. Before calling the ioctl, the field "tid" should be initialized with th= e id information for the timer which is to be selected. If there is no timer device with the specified id, the error ENODEV ("No such device") is returned. Implementation notes: Ioctl implemented in this patch has a pointer to a 'struct snd_timer_select' as its third argument. That is the reason why a corresponding definition was added in 'linux-user/syscall_types.h'. The rest of the implementation was straightforward.
