mysql_waitpid - Kill Process and Wait for Its Termination
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.
