Grid Redstone.png  Function commands.getBlockInfos
Available only to Command Computers as of ComputerCraft version 1.76, returns a numerically-indexed table containing information on the blocks within the specified world co-ordinates. Each sub-table is formatted per the output of commands.getBlockInfo():
  state = table state information
  name = string block's name,
  metadata = number block's metadata

A maximum of 4096 (2^12) blocks may be inspected at a time (for example, a 16x16x16 cube); the function will error if the block count exceeds this.

The blocks are returned in the order of lowest x-co-ord to highest x-co-ord, then lowest z-co-ord to highest z-co-ord, then lowest y-co-ord to highest y-co-ord; that is to say, west to east, then north to south, then lowest altitude to highest altitude.
