barrier_wait_cb()

static void barrier_wait_cb ( void *  cls, const char *  name, int  status  )

Functions of this type are to be given as acallback argument to GNUNET_TESTBED_barrier_wait().

The callback will be called when the barrier corresponding given in GNUNET_TESTBED_barrier_wait() is crossed or cancelled.

Parameters

cls	NULL
name	the barrier name
status	GNUNET_SYSERR in case of error while waiting for the barrier; GNUNET_OK if the barrier is crossed
