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:
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:
