designator to select a process which is waited for. The system call optionally returns siginfo_t which would be otherwise provided to SIGCHLD handler, as well as extended structure accounting for child and cumulative grandchild resource usage. Allow to get the current rusage information for non-exited processes as well, similar to Solaris. The explicit WEXITED flag is required to wait for exited processes, allowing for more fine-grained control of the events the waiter is interested in. Fix the handling of siginfo for WNOWAIT option for all wait*(2) family, by not removing the queued signal state. PR: standards/170346 Submitted by: "Jukka A.
