| 마지막으로 소스를 대충 보면, wait()를 하는 부분이 없네요. TestA가 daemon 형태로 re-parent한다면
상관없겠지만, 그렇지 않다면 아마 zombie 프로세스가 될 듯 합니다. zombie를 막으려면 daemon 형태로 만들거나,
wait()로 child process의 return을 받아야 합니다. 그리고 이 때, SIGCHLD를 비롯, signal
처리를 하려면 pthread_sigmask() 등을 써서, signal을 원하지 않은 thread에서는 해당 시그널이 발생하지
않도록 block시켜야 합니다. [링크 : http://kldp.org/node/103568] |
| All of these system calls are used to wait for state changes in a child
of the calling process,
and obtain information about the child whose state has changed. A state
change is considered to be: the child terminated; the child was stopped
by a signal; or
the child was resumed by a signal. In the case of a terminated child,
performing a wait allows the system to release the resources associated
with the child;
if a wait is not performed, then terminated the child remains in a
"zombie" state (see NOTES below).

| Kernel Threads Sometimes the process args will be unavailable; when this is happens, ps will instead print the executable name in brackets. This is correct, try execl(program_path, NULL) and you will see your process listed in brackets.

| state The state is given by a sequence of characters, for example, "RWNA". The first character indicates the run state of the process: D Marks a process in disk (or other short term, uninterruptible) wait. I Marks a process that is idle (sleeping for longer than about 20 seconds). L Marks a process that is waiting to acquire a lock. R Marks a runnable process. S Marks a process that is sleeping for less than about 20 seconds. T Marks a stopped process. W Marks an idle interrupt thread. Z Marks a dead process (a "zombie"). Additional characters after these, if any, indicate additional state information: + The process is in the foreground process group of its control terminal. < The process has raised CPU scheduling priority. E The process is trying to exit. J Marks a process which is in jail(2). The hostname of the prison can be found in /proc/<pid/status>. L The process has pages locked in core (for example, for raw I/O). N The process has reduced CPU scheduling priority (see setpriority(2)). s The process is a session leader. V The process is suspended during a vfork(2). W The process is swapped out. X The process is being traced or debugged. [링크 : http://www.gsp.com/cgi-bin/man.cgi?section=1&topic=ps] |
