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