| /** |
| * 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, 0x0003-0x007F) |
| * |
| * Module Nr Codes assigned |
| * MPI 7 0x0002-0x0010 |
