- _copy(master_fd, master_read=<function _read>, stdin_read=<function _read>)
- Parent copy loop.
Copies
pty master -> standard output (master_read)
standard input -> pty master (stdin_read)
- _open_terminal()
- Open pty master and return (master_fd, tty_name).
SGI and generic BSD version, for when openpty() fails.
- _read(fd)
- Default read function.
- _writen(fd, data)
- Write all the data to a descriptor.
- fork()
- fork() -> (pid, master_fd)
Fork and make the child a session leader with a controlling terminal.
- 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() -> (master_fd, slave_fd)
Open a pty master/slave pair, using os.openpty() if possible.
- select(...)
- select(rlist, wlist, xlist[, timeout]) -> (rlist, wlist, xlist)
Wait until one or more file descriptors are ready for some kind of I/O.
The first three arguments are lists 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.
- 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(argv, master_read=<function _read>, stdin_read=<function _read>)
- Create a spawned process.
