MYSQL_WAITPID(1)             MySQL Database System            MYSQL_WAITPID(1)

       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.

       This program is deprecated as of MySQL 5.6.19 and is removed in MySQL 5.7.

       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:

       ?   --help, -?, -I

           Display a help message and exit.

       ?   --verbose, -v

           Verbose mode. Display a warning if signal 0 could not be used and signal 1 is used instead.

       ?   --version, -V

           Display version information and exit.
