executing external commands from poco

[argoneus]

is there a Poco equivalent of the C++ system() function to execute an external command? i'm running against a limitation of system() and was wondering if Poco provided similar (perhaps more flexible) functionality. Thank you.

See the Process class in the Foundation library, and the Process::launch() member function in the different variants.

To get system() - like behaviour with Process::launch(), you'll have to explicitly create a shell process that executes a command.

On Windows:

Code: Select all


Process: :Args args;
args.push_back("/C");
args.push_back("DIR");
Process: :launch("CMD.EXE", args);
...


On Unix:

Code: Select all


Process: :Args args;
args.push_back("-c");
args.push_back("ls");
Process: :launch("sh", args);
...


There is also another variant of Process::launch() that supports I/O redirection using pipes and iostreams.
