+The first form is appropriate when the SNL variable is a scalar.
+However, it can also be an array (each of whose elements may be
+assigned to a different process variable). In this case, the
+single argument form returns whether *all* :c:func:`pvGet` operations
+for elements of the array have completed (missing arguments are
+implicitly set to ``0``). If ``any`` is ``TRUE``, then
+the function returns whether *any* get has completed since the last
+call. If ``pComplete`` is non-NULL, it should be an array of
+at least the array length of the SNL variable and its elements indicate
+whether the corresponding :c:func:`pvGet` has completed.
