| /* |
| * Name: getNonKeyAttribute |
| * Input: FILE ptr |
| * Output: character string handle |
| * Return: GET_NON_KEY_ATTRIBUTE_SUCCESS, or |
| * GET_NON_KEY_ATTRIBUTE_ALLOCATION_FAILURE, |
| * GET_NON_KEY_ATTRIBUTE_GET_STRING_FAILURE |
| * Description: Reads a non-key attribute from the current position of the |
| * file pointer. A non-key attribute is defined to be a |
| * white-space delimited string. The read will not cross an |
| * end-of-line indicated by a new line '\n' or carriage return |
| * '\r'. The routine is a match for the getNonKeyAttribute() |
| * routine and simply calls the getFloat() routine to read the |
| * key value from the file. |
| * Calls: errorMessage() |
| * getFloat() |
