Detailed Description

Convert vector<string> args to dynamically allocated (argc, argv) pair which will be freed when the instance is destroyed.

This is useful for passing leftover NidasApp command-line arguments to getopt() functions. The argv array includes the process name, as expected by getopt().

NidasApp app('data_dump');
// Parse standard arguments and leave the rest.
ArgVector args = app.parseArgs(ArgVector(argv, argv+argc));
NidasAppArgv left(argv[0], args);
int opt_char;
while ((opt_char = getopt(left.argc, left.argv, "...")) != -1) {
   ...
}
