+/**
+ * Error code layout.
+ *
+ * Currently we try to keep all error codes within the negative space of 16
+ * bytes signed integers to support all platforms (-0x0000 - -0x8000). 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  - Intentionally not used
+ * 3 bits - High level module ID
+ * 5 bits - Module-dependent error code
+ * 6 bits - Low level module errors
+ * 1 bit  - Intentionally not used
+ *
+ * Low-level module errors (0x007E-0x0002)
+ *
+ * Module   Nr  Codes assigned 
+ * MPI       7  0x0002-0x0010
