.SH DESCRIPTION
.B pmpause
sleeps indefinitely, until interrupted by SIGKILL.
.PP
.B pmsleep
sleeps for the specified
.I interval.
The
.I interval
argument follows the syntax described in
.BR PCPIntro (1)
for 
.B \-t,
and in the simplest form may be an unsigned integer 
or floating point constant 
(the implied units in this case are seconds).
.SH DIAGNOSTICS
The exit status is 0 for success, or 1 for a malformed command line.
If the underlying
.BR nanosleep (2)
system call fails, an errno is returned.
