spawn_with_fds_async

Description:

[ Version ( since = "0.62" ) ]
public async void spawn_with_fds_async (string? working_directory, string[] argv, string[]? envv, int[]? fds, int[]? map_fds, SpawnFlags spawn_flags, owned SpawnChildSetupFunc? child_setup, int timeout, Cancellable? cancellable)

Starts the specified command under the pseudo-terminal this.

The argv and envv lists should be null-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 STDOUT_TO_DEV_NULL, STDERR_TO_DEV_NULL, and 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 LEAVE_DESCRIPTORS_OPEN is not supported; and DO_NOT_REAP_CHILD will always be added to spawn_flags.

If fds is not null, the child process will map the file descriptors from fds according to map_fds; map_fds.length must be less or equal to fds.length. 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 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 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 Pty, and watch_child for more information.

Parameters:

this	a Pty

fds	an array of file descriptors, or `null`
map_fds	an array of integers, or `null`
spawn_flags	flags from SpawnFlags
