|  | * Error code layout. | 
|  | * | 
|  | * Currently we try to keep all error codes within the negative space of 16 | 
|  | * bits signed integers to support all platforms (-0x0001 - -0x7FFF). In | 
|  | * addition we'd like to give two layers of information on the error if | 
|  | * possible. | 
|  | * | 
|  | * For that purpose the error codes are segmented in the following manner: | 
|  | * | 
|  | * 16 bit error code bit-segmentation | 
|  | * | 
|  | * 1 bit  - Unused (sign bit) | 
|  | * 3 bits - High level module ID | 
|  | * 5 bits - Module-dependent error code | 
|  | * 7 bits - Low level module errors | 
|  | * | 
|  | * For historical reasons, low-level error codes are divided in even and odd, | 
|  | * even codes were assigned first, and -1 is reserved for other errors. | 
|  | * | 
|  | * Low-level module errors (0x0002-0x007E, 0x0001-0x007F) |
