Hey everyone,
Since there is not yet a Boost.Process library, does anyone have a suggestion for a lightweight cross-platform C++ library for launching and monitoring (i.e. being able to tell if they die) child processes?
I've put the code from the recent boostcon "boost process" presentation that Boris Schaeling and I gave at:
https://github.com/JeffFlinn/boost-process
Initial documentation is at:
https://docs.google.com/document/pub?id=1qdpxcJB51WMuNYlKYPkPcZZGuPj7zmeUPIp...
The intent is to get this completed and ask for review this summer. The areas needing work are:
I've read the current (clearly incomplete w.i.p.) doc and parsed the
Very w.i.p. :-(
headers and I like the design so far.
Thanks.
However, I can't find a way to be notified if a child process did end, by getting to the end of the program or by having crashed or by having being shut down by external processes, the OS or the user.
Did I miss something? If not, what is supposed to happen in the parent process if a child do get to an end (whatever the cause)?
This area needs more work, there is just enough there to support our current needs. The boost::process::monitor::join method is used to wait for a child process to 'finish' due to whatever cause, which returns the exit code on windows and the status on posix. There is a template method boost::process::monitor::join<class EXCEPTION> that throws a default constructed exception of the supplied type when join returns a non-zero value. Can you provide a more concrete set of requirements? The previous iteration(s) of process had an asynch wait facility that may be able to be used with the latest design. Boris, do you have any ideas here? Jeff
