G'day, can anyone tell me how 'ls' knows whether a file is a regular file or a pipe ? When i do a stat(2) call on the file, it is returned as a regular file. What tricks does ls perform ? Also, a question about curses, whenever I call one of the input routines, say getstr(), wscanw(), etc, the program hangs while reading data in read(2). I have called initscr() and various other curses calls BEFORE getting to these (successfully too :/ ). The only thing the program responds to after this is manual sending of signals to the process :-(. Do i need to make any *other* calls to get these to work or is it a deeper, more serious problem ? My environ. is a pyramid 9825, OSx5.1, BSD universe. thanks, -avalon p.s. sorry for the crosspost but the curses question/ problem is still unresolved after posting to c.u.q.
