.SH "DESCRIPTION"
|
|
.PP
|
|
\fBmariadb-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
|
|
\fBmariadb-waitpid\fR
|
|
like this:
|
|
.sp
|
|
.if n \{\
|
|
.RS 4
|

.\}
|
|
.nf
|
|
shell> \fBmariadb-waitpid [\fR\fB\fIoptions\fR\fR\fB] \fR\fB\fIpid\fR\fR\fB \fR\fB\fIwait_time\fR\fR

|
|
.if n \{\
|
|
.RE
|
|
.\}
|
|
.PP
|
|
\fBmariadb-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,
|
|
\fBmariadb-waitpid\fR
|
|
returns 0\&. Otherwise, it returns 1\&.
|
|
.PP
|
|
If the
|
|
kill()
|
|
system call cannot handle signal 0,
|
|
\fBmariadb-waitpid()\fR
|
|
uses signal 1 instead\&.
|
