NAME

       pmpause, pmsleep - portable subsecond-capable sleep

SYNOPSIS

       $PCP_BINADM_DIR/pmpause [-w where]
       $PCP_BINADM_DIR/pmsleep [-w where] interval

DESCRIPTION

       pmpause sleeps indefinitely, until interrupted by SIGKILL.

       pmsleep  sleeps  for  the  specified  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).

       The  -w  option  is  provided to allow annotation of scripts with multiple uses of pmpause
       and/or pmsleep to identify a particular use in the process's arguments, e.g. as visible to
       ps(1).

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.
