April 2024 - This site, and Kamaelia are being updated. There is significant work needed, and PRs are welcome.
For examples and more explanations, see the module level docs.
UnixProcess2(command[,buffersize][,outpipes][,inpipes][,boxsizes])
-> new UnixProcess2 component.
Starts the specified command as a separate process. Data can be sent
to stdin and received from stdout. Named pipes can also be created for
extra channels to get data to and from the process.
Keyword arguments:
- command -- command line string that will invoke the subprocess
- buffersize -- bytes size of buffers on the pipes to and from the process (default=32768)
- outpipes -- dict mapping named-pipe-filenames to outbox names (default={})
- inpipes -- dict mapping named-pipe-filenames to inbox names (default={})
- boxsizes -- dict mapping inbox names to box sizes (default={})
Inboxes
- control : Shutdown signalling
- inbox : Binary string data to go to STDIN of the
process.
Outboxes
- outbox : Binary string data from STDOUT of the
process
- signal : Shutdown signalling
- _shutdownPipes : For shutting down any named pipes
used for output
- error : Binary string data from STDERR of the
process
Methods defined here
Warning!
You should be using the inbox/outbox interface, not these methods
(except construction). This documentation is designed as a roadmap as to
their functionalilty for maintainers and new component developers.
__init__(self, command[, buffersize][,
outpipes][, inpipes][, boxsizes])
x.__init__(...) initializes x; see x.__class__.__doc__ for
signature
childrenDone(self)
Unplugs any children that have terminated, and returns true if there
are no running child components left (ie. their microproceses have
finished)
main(self)
main loop
setupNamedInPipes(self,
pipeshutdown)
setupNamedOutPipes(self,
pipeshutdown)
Feedback
Got a problem with the documentation? Something unclear that could be
clearer? Want to help improve it? Constructive criticism is very welcome
- especially if you can suggest a better rewording!
Please leave you feedback here in reply to the documentation thread in the
Kamaelia blog.
