| /* This file defines variables accessor functions that are globally used |

| * accessible through the accessor functions defined here. The purpose of |
| * doing so is for cleaner coding style. Reducing the amount of global |
| * variables will lessen the likelihood of multiple variables of the same |
| * name being declared in different files, and thus will avoid compiler |
| * error. |
