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.
