= Component usage =

== Object ==

{{{
soclib::common::ProcessWrapper *process;
}}}

== Instanciation ==


{{{
    soclib::common::ProcessWrapper(
        const std::string &cmd,
        const std::vector<std::string> &argv );
}}}

 cmd::
   The command to launch, it will be looked for in $PATH
 argv::
   The argv in a standart unix style. argv[0] should look like cmd.

== Usage ==

{{{
    std::vector<std::string> argv;
    argv.push_back("date");
    argv.push_back("+%s");
    soclib::common::ProcessWrapper process("date", argv);

    char buffer[128];
    process.read( buffer, 128 );
    std::cout << "Date is " << buffer << " seconds since EPOCH" << std::endl;
