[PATCH 12/12] linux-user: Add support for selected alsa timer instructions using ioctls |
Date: |
Thu, 9 Jan 2020 13:59:23 +0100 |
This patch implements functionalities of following ioctls:
SNDRV_TIMER_IOCTL_START - Start selected alsa timer
Starts the timer device that is selected. The third ioctl's argument is
ignored. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT"
should be called first to select the timer that is to be started. If no
timer is selected, the error EBADFD ("File descriptor in bad shape")
is returned.
SNDRV_TIMER_IOCTL_STOP - Stop selected alsa timer
Stops the timer device that is selected. The third ioctl's argument is
ignored. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT"
should be called first to select the timer that is to be stopped. If no
timer is selected, the error EBADFD ("File descriptor in bad shape")
is returned.
SNDRV_TIMER_IOCTL_CONTINUE - Continue selected alsa timer
Continues the timer device that is selected. The third ioctl's argument is
ignored. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT"
should be called first to select the timer that is to be continued. If no
timer is selected, the error EBADFD ("File descriptor in bad shape")
is returned.
SNDRV_TIMER_IOCTL_PAUSE - Pause selected alsa timer
Pauses the timer device that is selected. The third ioctl's argument is
ignored. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT"
should be called first to select the timer that is to be paused. If no
timer is selected, the error EBADFD ("File descriptor in bad shape")
is returned.
Implementation notes:
Since all of the implemented ioctls have NULL as their third argument,
their implementation was straightforward.
