MYSQL_WAITPID(1)                     MariaDB Database System                     MYSQL_WAITPID(1)

NAME
       mysql_waitpid - kill process and wait for its termination

SYNOPSIS
       mysql_waitpid [options] pid wait_time

DESCRIPTION
       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:

       •   --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.
