| Just encountered a case where wait(4) + WNOHANG do not fail with | expected ECHILD when there is no process to wait. See man 2 wait ... When the WNOHANG option is specified and no processes wish to report status, wait4() returns a process id of 0. If you specified WNOHANG it is not an error that there are no processes available, there are just no processes... kre
