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_timemysql_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.
