[−][src]Struct alsa::direct::pcm::SyncPtrStatus
Read PCM status via a simple kernel syscall, bypassing alsa-lib.
If Status is not available on your architecture, this is the second best option.
Methods
impl SyncPtrStatus[src]
pub unsafe fn sync_ptr(
fd: RawFd,
hwsync: bool,
appl_ptr: Option<Frames>,
avail_min: Option<Frames>
) -> Result<Self>[src]
fd: RawFd,
hwsync: bool,
appl_ptr: Option<Frames>,
avail_min: Option<Frames>
) -> Result<Self>
Executes sync_ptr syscall.
Unsafe because
- setting appl_ptr and avail_min might make alsa-lib confused
- no check that the fd is really a PCM
pub fn hw_ptr(&self) -> Frames[src]
pub fn state(&self) -> State[src]
pub fn htstamp(&self) -> timespec[src]
