Hello, Sorry, i just realized that the following is obviously wrong: > but this cannot work as it is defined as follows: > void Process::detach(void) { attach("/dev/null"); }
This calls attach with "dev/null". Anyway, i still do not get it to work so any help is apprecicated. Example: main() { cout << "before creating the daemon" << endl; // ? how to setup the parent to wait (or not) for the child? // cannot use detach because it would close all handles of the child. Process::attach("what goes here?"); If ("what goes here?") { char buffer[32]; cout << "i am the child" << endl; cin.getline(buffer, sizeof(buffer)); cout << "Child: You entered:" << buffer << "\nDone:" << endl; exit(0); } else { cout << "i am the parent - Done" << endl; exit(0); } } Regards Wolfgang Am Mittwoch, 9.
