I have a program that calls fork() followed by execl(). When the child
process terminates, the signal handler gets called in the parent, which
starts a new child process in the same manner. Occasionally, the parent
process will have need to call system() whilst there is already a child
process running somewhere. When system() returns, it fires the signal
handler too, which is undesired.
- When the signal handler is called, how can I tell which child process
is generating it.
- With multiple child processes, if a second child terminates while the
parent is in a signal handler due to the termination of the second
child, is there any chance of missing the second signal?
