When testing my file duplicate finder one of my test cases is to create a socket, a pipe, a character device and a block device file. My racket program gets a system error: No such device or address; errno=6 when dealing with a socket. Or if it is a pipe then it waits for input. I think functionality should be added in Racket. What's about something like this? socket-exists pipe-exists block-device-exists character-device-exists -- Manfred -- Manfred ____________________ Racket Users list: http://lists.racket-lang.org/users
