Struct alsa::direct::pcm::SyncPtrStatus

source · 
pub struct SyncPtrStatus(/* private fields */);
Expand description

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.

Implementations§

source§

impl SyncPtrStatus

source

pub unsafe fn sync_ptr( 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

source

pub fn state(&self) -> State

pub fn htstamp(&self) -> timespec
