mysql_waitpid

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 understands 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.
