gp.link.zone

Syntax

z = gp.link.zone(gp)

Get the first zone connected to this gridpoint. Use the four intrinsics gp.link.zone, gp.link.index, zone.link.zone, and zone.link.index to iterate through every zone connected to a gridpoint.

Returns:z - a pointer to the first zone connected to the gridpoint Arguments:gp - a zone gridpoint pointer

Usage Example

The following code fragment shows how to traverse all the zones connected to a single gridpoint.

local zone = gp.link.zone(gp)
local index = gp.link.index(gp)
loop while zone # null
   (Do something with that zone)
   local index_copy = zone.link.index(zone,index)
   zone = zone.link.zone(zone,index)
   index = index_copy
end_loop
