Starts the specified command under the pseudo-terminal pty. 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 that G_SPAWN_DO_NOT_REAP_CHILD will always be added to spawn_flags.
Note that all open file descriptors will be closed in the child. If you want to keep some 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.
See Pty.new, Spawn.async and Terminal.watchChild for more information.
