+.SH "DESCRIPTION"
+.PP
+\fBmysql_waitpid\fR
+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\&.
+.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 \{\
