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.
