.SH NAME
pause \- suspend process until signal
.SH SYNOPSIS
.LP
.nf
#include <unistd.h>
\fBint\fR \fBpause\fR(\fBvoid\fR);
.fi
.SH DESCRIPTION
.sp
.LP
The \fBpause()\fR function suspends the calling process until it receives a
signal. The signal must be one that is not currently set to be ignored by the
calling process.
.sp
.LP
If the signal causes termination of the calling process, \fBpause()\fR does not
return.
.sp
.LP
If the signal is caught by the calling process and control is returned from the
signal-catching function (see \fBsignal\fR(3C)), the calling process resumes
execution from the point of suspension.
.SH RETURN VALUES
.sp
.LP
Since \fBpause()\fR suspends thread execution indefinitely unless interrupted
by a signal, there is no successful completion return value. If interrupted,
it returns \fB\(mi1\fR and sets \fBerrno\fR to indicate the error.
.SH ERRORS
.sp
.LP
The \fBpause()\fR function will fail if:
.sp
.ne 2
.na
\fB\fBEINTR\fR\fR
.ad
.RS 9n
A signal is caught by the calling process and control is returned from the
signal-catching function.
