pty

Pseudo terminal utilities.

Functions

fork

fork()

  fork() -> (pid, master_fd)
      Fork and make the child a session leader with a controlling terminal.

master_open

master_open()

  master_open() -> (master_fd, slave_name)
      Open a pty master and return the fd, and the filename of the slave end.
      Deprecated, use openpty() instead.

openpty

openpty()

  openpty() -> (master_fd, slave_fd)
      Open a pty master/slave pair, using os.openpty() if possible.

select

select(rlist, wlist, xlist, timeout=None, /)

  Wait until one or more file descriptors are ready for some kind of I/O.

  The first three arguments are iterables of file descriptors to be waited for:
  rlist -- wait until ready for reading
  wlist -- wait until ready for writing
  xlist -- wait for an "exceptional condition"
  If only one kind of condition is required, pass [] for the other lists.

  A file descriptor is either a socket or file object, or a small integer
  gotten from a fileno() method call on one of those.

  The optional 4th argument specifies a timeout in seconds; it may be
  a floating point number to specify fractions of seconds.  If it is absent
  or None, the call will never time out.

  The return value is a tuple of three lists corresponding to the first three
  arguments; each contains the subset of the corresponding file descriptors
  that are ready.

  *** IMPORTANT NOTICE ***
  On Windows, only sockets are supported; on Unix, all file
  descriptors can be used.

slave_open

slave_open(tty_name)

  slave_open(tty_name) -> slave_fd
      Open the pty slave and acquire the controlling terminal, returning
      opened filedescriptor.
      Deprecated, use openpty() instead.

spawn

spawn(argv, master_read=<function _read at 0x7f0225d463a0>, stdin_read=<function _read at 0x7f0225d463a0>)

  Create a spawned process.
