It uses the kill() system call and Unix signals, so it runs on Unix and Unix\-like systems\&. .PP Invoke \fBmysql_waitpid\fR like this: .sp .if n \{\ .RS 4 .\} .nf shell> \fBmysql_waitpid [\fR\fB\fIoptions\fR\fR\fB] \fR\fB\fIpid\fR\fR\fB \fR\fB\fIwait_time\fR\fR .fi .if n \{\ .RE .\} .PP \fBmysql_waitpid\fR sends signal 0 to the process identified by \fIpid\fR and waits up to \fIwait_time\fR seconds for the process to terminate\&. \fIpid\fR and \fIwait_time\fR must be positive integers\&. .PP If process termination occurs within the wait time or the process does not exist, \fBmysql_waitpid\fR returns 0\&. Otherwise, it returns 1\&. .PP If the kill() system call cannot handle signal 0, \fBmysql_waitpid()\fR uses signal 1 instead\&. .PP \fBmysql_waitpid\fR supports the following options: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} .\" mysql_waitpid: help option .\" help option: mysql_waitpid \fB\-\-help\fR, \fB\-?\fR, \fB\-I\fR .sp Display a help message and exit\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} .\" mysql_waitpid: verbose option .\" verbose option: mysql_waitpid \fB\-\-verbose\fR, \fB\-v\fR .sp Verbose mode\&.
