Struct tokio_pty_process::AsyncPtyMaster [−][src]
pub struct AsyncPtyMaster(_);
A handle to a pseudo-TTY master that can be interacted with asynchronously.
This type implements both AsyncRead
and AsyncWrite
.
Methods
impl AsyncPtyMaster
[src]
impl AsyncPtyMaster
pub fn open() -> Result<Self, Error>
[src]
pub fn open() -> Result<Self, Error>
Open a pseudo-TTY master.
This function performs the C library calls posix_openpt()
,
grantpt()
, and unlockpt()
. It also sets the resulting pseudo-TTY
master handle to nonblocking mode.
