+* CHK_WNCFE( condition-to-check, fail|void|null|resume )
+*
+* 'fail' if you want FATAL_WNC_ERROR to be called.
+* 'void' if you want to execute a void return
+* 'null' if you want to execute a null return
+* 'resume' if you simply want to resume program execution
+*
+* There are several settings that control how FATAL_WNC_ERROR behaves:
+* 1) RESETON_FE determines if the system will reset or hang.
+* 2) DISPLAY_FE determine if an error message is generated or not
+*
+* The DISPLAY_FE setting determines if a failure message is displayed.
+* If set to 1, user sees this messageo:
+*
+* WNC FAILED @ source-file-name:source-file-line-number
+*
+* if not set, nothing is displayed.
