Array parameters

[Doug Gwyn (VLD/VMB)]

No, arrays cannot be passed as actual arguments to a function
but only their addresses.
	function( a ) int a[5][6]; { ... }
has just one pointer datum passed to it, not 30 ints.  The difference
is significant; due to C's "pass-by-value" design, in the actual case
"function" can modify the caller's array while in the incorrect case
(entire array as argument) it could only modify its own local copy of
the array.
