About SIGCHLD
When the SIGCHLD is sent?
SIGCHLD is sent either a child exits spontaneously (e.g. exit(0)) or it is killed ? thank you in advance

On POSIX-compliant platforms, SIGCHLD is the signal sent by computer programs when a child process terminates. The symbolic constant for SIGCHLD is defined in the header file signal.h. Symbolic signal names are used because signal numbers can vary across platforms.

A process must install a signal handler to receive the signal at all. By default, the signal is not sent. If the signal is being caught, it will be delivered whenever a child process changes status. By "status" we mean any of the status values returned by wait(). This includes a process that has exited due to explicitly calling exit() or being killed by the kernel. It also includes processes that stop or continue. This latter behavior is used by job control shells and by debuggers.
