  • Closed as program error.

Error description

  • When a process has a pipe opened, the two FDs are listed
    under /proc/PID/fd ( along with any other FDs ).
    
    When the command : find /proc/7656458/fd/
    is run, error output as follows is seen.
    
    /proc/7656458/fd/4 is not valid
    
    However, all non-pipe FDs list correctly.
    
    The following program should be able to create two FDS
    3 and 4.
    main()
    {
    
            int fdpip[2];
            pipe(fdpip);
    
            sleep(-1);
    
    }
    
    The FDs 0,1 and 2 will list correctly but 3 and 4 will
    not.
