+.SH NAME
+pause \- suspend the thread until a signal is received
+.SH SYNOPSIS
+.LP
+\fB#include <unistd.h>
+.br
+.sp
+int pause(void);
+.br
+\fP
+.SH DESCRIPTION
+.LP
+The \fIpause\fP() function shall suspend the calling thread until
+delivery of a signal whose action is either to execute a
+signal-catching function or to terminate the process.
+.LP
+If the action is to terminate the process, \fIpause\fP() shall not
+return.
+.LP
+If the action is to execute a signal-catching function, \fIpause\fP()
+shall return after the signal-catching function
+returns.
+.SH RETURN VALUE
+.LP
+Since \fIpause\fP() suspends thread execution indefinitely unless
+interrupted by a signal, there is no successful completion
+return value. A value of -1 shall be returned and \fIerrno\fP set
+to indicate the error.
+.SH ERRORS
+.LP
+The \fIpause\fP() function shall fail if:
+.TP 7
+.B EINTR
+A signal is caught by the calling process and control is returned
+from the signal-catching function.
+.sp
+.LP
+\fIThe following sections are informative.\fP
+.SH EXAMPLES
+.LP
+None.
+.SH APPLICATION USAGE
+.LP
+Many common uses of \fIpause\fP() have timing windows. The scenario
+involves checking a condition related to a signal and, if
+the signal has not occurred, calling \fIpause\fP(). When the signal
+occurs between the check and the call to \fIpause\fP(), the
+process often blocks indefinitely. The \fIsigprocmask\fP() and \fIsigsuspend\fP()
+functions can be used to avoid this type of problem.
+.SH RATIONALE
+.LP
+None.
+.SH FUTURE DIRECTIONS
+.LP
+None.
