source§impl Pty
impl Pty
sourcepub fn new_sync(
flags: PtyFlags,
cancellable: Option<&impl IsA<Cancellable>>,
) -> Result<Pty, Error>
pub fn new_sync( flags: PtyFlags, cancellable: Option<&impl IsA<Cancellable>>, ) -> Result<Pty, Error>
Allocates a new pseudo-terminal.
You can later use fork() or the g_spawn_async() family of functions to start a process on the PTY.
If using fork(), you MUST call vte_pty_child_setup() in the child.
If using g_spawn_async() and friends, you MUST either use vte_pty_child_setup() directly as the child setup function, or call vte_pty_child_setup() from your own child setup function supplied.
When using vte_terminal_spawn_sync() with a custom child setup function, vte_pty_child_setup() will be called before the supplied function; you must not call it again.
Also, you MUST pass the [glib::SpawnFlags::DO_NOT_REAP_CHILD
][crate::glib::SpawnFlags::DO_NOT_REAP_CHILD] flag.
Note also that [glib::SpawnFlags::STDOUT_TO_DEV_NULL
][crate::glib::SpawnFlags::STDOUT_TO_DEV_NULL], [glib::SpawnFlags::STDERR_TO_DEV_NULL
][crate::glib::SpawnFlags::STDERR_TO_DEV_NULL],
and [glib::SpawnFlags::CHILD_INHERITS_STDIN
][crate::glib::SpawnFlags::CHILD_INHERITS_STDIN] are not supported, since stdin, stdout
and stderr of the child process will always be connected to the PTY.
Note that you should set the PTY’s size using vte_pty_set_size() before
spawning the child process, so that the child process has the correct
size from the start instead of starting with a default size and then
shortly afterwards receiving a
§flags
flags from #VtePtyFlags
§cancellable
a #GCancellable, or None
§Returns
a new #VtePty, or None

sourcepub fn builder() -> PtyBuilder
pub fn builder() -> PtyBuilder
Creates a new builder-pattern struct instance to construct Pty
objects.
This method returns an instance of PtyBuilder
which can be used to create Pty
objects.

sourcepub fn fd(&self) -> BorrowedFd<'_>
pub fn fd(&self) -> BorrowedFd<'_>
§Returns
the file descriptor of the PTY master in @self. The file descriptor belongs to @self and must not be closed or have its flags changed
sourcepub fn foreign_sync(
fd: OwnedFd,
cancellable: Option<&impl IsA<Cancellable>>,
) -> Result<Pty, Error>
pub fn foreign_sync( fd: OwnedFd, cancellable: Option<&impl IsA<Cancellable>>, ) -> Result<Pty, Error>
Creates a new #VtePty for the PTY master @fd.
No entry will be made in the lastlog, utmp or wtmp system files.
Note that the newly created #VtePty will take ownership of @fd and close it on finalize.
§fd
a file descriptor to the PTY

a #GCancellable, or None

a new #VtePty for @fd, or None

Like vte_pty_spawn_with_fds_async(), except that this function does not allow passing file descriptors to the child process. See vte_pty_spawn_with_fds_async() for more information.

pub fn spawn_future<Q: Fn() + 'static>( &self, working_directory: Option<&str>, argv: &[&str], envv: &[&str], spawn_flags: SpawnFlags, child_setup: Q, timeout: i32, ) -> Pin<Box_<dyn Future<Output = Result<Pid, Error>> + 'static>>
sourcepub unsafe fn spawn_with_fds_async<P: FnOnce(Result<Pid, Error>) + 'static, Q: Fn() + 'static>(
&self,
working_directory: Option<&str>,
argv: &[&str],
envv: &[&str],
fds: Vec<OwnedFd>,
map_fds: &[RawFd],
spawn_flags: SpawnFlags,
child_setup: Q,

callback: P,

pub unsafe fn spawn_with_fds_async<P: FnOnce(Result<Pid, Error>) + 'static, Q: Fn() + 'static>( &self, working_directory: Option<&str>, argv: &[&str], envv: &[&str], fds: Vec<OwnedFd>, map_fds: &[RawFd], spawn_flags: SpawnFlags, child_setup: Q, timeout: i32, cancellable: Option<&impl IsA<Cancellable>>, callback: P, )
§Safety
The map_fds have to make sense.
Starts the specified command under the pseudo-terminal @self.
The @argv and @envv lists should be None
-terminated.
The “TERM” environment variable is automatically set to a default value,
but can be overridden from @envv.
@pty_flags controls logging the session to the specified system log files.
Note also that [glib::SpawnFlags::STDOUT_TO_DEV_NULL
][crate::glib::SpawnFlags::STDOUT_TO_DEV_NULL], [glib::SpawnFlags::STDERR_TO_DEV_NULL
][crate::glib::SpawnFlags::STDERR_TO_DEV_NULL],
and [glib::SpawnFlags::CHILD_INHERITS_STDIN
][crate::glib::SpawnFlags::CHILD_INHERITS_STDIN] are not supported in @spawn_flags, since
stdin, stdout and stderr of the child process will always be connected to
the PTY. Also [glib::SpawnFlags::LEAVE_DESCRIPTORS_OPEN
][crate::glib::SpawnFlags::LEAVE_DESCRIPTORS_OPEN] is not supported; and
[glib::SpawnFlags::DO_NOT_REAP_CHILD
][crate::glib::SpawnFlags::DO_NOT_REAP_CHILD] will always be added to @spawn_flags.
If @fds is not None
, the child process will map the file descriptors from
@fds according to @map_fds; @n_map_fds must be less or equal to @n_fds.
This function will take ownership of the file descriptors in @fds;
you must not use or close them after this call. All file descriptors in @fds
must have the FD_CLOEXEC flag set on them; it will be unset in the child process
before calling man:execve(2). Note also that no file descriptor may be mapped
to stdin, stdout, or stderr (file descriptors 0, 1, or 2), since these will be
assigned to the PTY. All open file descriptors apart from those mapped as above
will be closed when execve() is called.
Beginning with 0.60, and on linux only, and unless VTE_SPAWN_NO_SYSTEMD_SCOPE
is
passed in @spawn_flags, the newly created child process will be moved to its own
systemd user scope; and if VTE_SPAWN_REQUIRE_SYSTEMD_SCOPE
is passed, and creation
of the systemd user scope fails, the whole spawn will fail.
You can override the options used for the systemd user scope by
providing a systemd override file for ‘vte-spawn-.scope’ unit. See man:systemd.unit(5)
for further information.
See vte_pty_new(), and vte_terminal_watch_child() for more information.
