rox.proxy | index

`Given a pair of pipes with a python process at each end, this module
allows one end to make calls on the other. This is used by the su module
to allow control of a subprocess running as another user, but it may also
be useful in other situations. The caller end should use the master_proxy
module.
EXPERIMENTAL.`

Functions
`` |  | 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 sequences 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 and OpenVMS, only sockets are supported; on Unix, all file descriptors can be used.`
