spawn_with_fds_async

A convenience function that wraps creating the Pty and spawning the child process on it.

See Pty.sync, spawn_with_fds_async, and spawn_async.end for more information.

When the operation is finished successfully, callback will be called with the child Pid, and a null Error. The child PID will already be watched via watch_child.

When the operation fails, callback will be called with a -1 Pid, and a non-null Error containing the error information.

Note that g_spawn_stdout_to_dev_null, g_spawn_stderr_to_dev_null, and g_spawn_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.

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.

Note that all open file descriptors apart from those mapped as above will be closed in the child. (If you want to keep some other file descriptor open for use in the child process, you need to use a child setup function that unsets the FD_CLOEXEC flag on that file descriptor manually.)

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.

Note that if this has been destroyed before the operation is called, callback will be called with a null this; you must not do anything in the callback besides freeing any resources associated with user_data, but taking care not to access the now-destroyed Terminal. Note that in this case, if spawning was successful, the child process will be aborted automatically.

Beginning with 0.52, sets PWD to working_directory in order to preserve symlink components. The caller should also make sure that symlinks were preserved while constructing the value of working_directory, e.g. by using get_current_directory_uri, get_current_dir or get_current_dir_name.
