mysql_waitpid - kill process and wait for its termination
mysql_waitpid [options] pid wait_time
mysql_waitpid signals a process to terminate and waits for the process to exit. It uses the kill() system call and Unix signals, so it runs on Unix and Unix-like systems. Invoke mysql_waitpid like this: shell> mysql_waitpid [options] pid wait_time mysql_waitpid sends signal 0 to the process identified by pid and waits up to wait_time seconds for the process to terminate. pid and wait_time must be positive integers. If process termination occurs within the wait time or the process does not exist, mysql_waitpid returns 0. Otherwise, it returns 1. If the kill() system call cannot handle signal 0, mysql_waitpid() uses signal 1 instead. mysql_waitpid supports the following options: o --help, -?, -I Display a help message and exit. o --verbose, -v Verbose mode. Display a warning if signal 0 could not be used and signal 1 is used instead. o --version, -V Display version information and exit.
