Since you are going to (eventually) load in a program image have to do several system calls to create the process isn't likely to be a problem. So using separate calls for each property isn't really an issue and solves the horrid problem of the API structure. So you could create an embryonic process that inherits a lot of stuff from the current process, the do actions that sort out the fds, argv, namespace etc. Finally running the new program. It would probably make implement posix_spawn() easier. David - Registered Address Lakeside, Bramley Road, Mount Farm, Milton Keynes, MK1 1PT, UK Registration No: 1397386 (Wales)
