.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 \{\
.sp -1
.IP \(bu 2.3
.\}
