Hello, I suggest following features as additions to boost.process: - status should also check for continued state with WIFCONTINUED and return SIGCONT as signal - posix_child::wait should support the flags WUNTRACED and WCONTINUED - new satic function static std::pair< posix_child, status > posix_child::wait() which supports the flags WNOHANG, WUNTRACED and WCONTINUED (used inside of SIGCHLD signal handler) - posix_child shoulkd implement following functions exist -> ::kill( pid, 0), stopp -> ::kill( pid, SIGSTOP), continue -> ::kill( pid, SIGCONT), terminate -> ::kill( pid, SIGTERM), kill -> ::kill( pid, SIGKILL), usr1 -> ::kill( pid, SIGUSR1) and usr2 -> ::kill( pid, SIGUSR2) - posix_launcher should support rlimits -> ::set_relimit(), priority -> ::setpriority(), process group id -> ::setpgid(), session leader -> ::setsid(), creation mask -> ::umask() regards, Oliver
