I am guessing your shell does not support this. You would need bash or ksh93.

_lwp_cond_signal

_lwp_cond_signal(2)						   System Calls 					       _lwp_cond_signal(2)

NAME

       _lwp_cond_signal, _lwp_cond_broadcast - signal a condition variable

SYNOPSIS

       #include <sys/lwp.h>

       int _lwp_cond_signal(lwp_cond_t *cvp);

       int _lwp_cond_broadcast(lwp_cond_t *cvp);

DESCRIPTION

       The _lwp_cond_signal() function unblocks one LWP that is blocked on the LWP condition variable pointed to by cvp.

       The _lwp_cond_broadcast() function unblocks all LWPs that are blocked on the LWP condition variable pointed to by cvp.

       If no LWPs are blocked on the LWP condition variable, then _lwp_cond_signal() and _lwp_cond_broadcast() have no effect.

       Both  functions	should	be called under the protection of the same LWP mutex lock that is used with the LWP condition variable being  sig-
       naled. Otherwise, the condition variable may be signalled between the test of the associated condition and  blocking  in  _lwp_cond_wait().
       This can cause an infinite wait.

RETURN VALUES

       Upon successful completion, 0 is returned. A non-zero value indicates an error.

ERRORS

       The _lwp_cond_signal() and _lwp_cond_broadcast() functions will fail if:

       EINVAL	       The cvp argument points to an invalid LWP condition variable.

       EFAULT	       The cvp argument points to an invalid address.
