/**
|
* 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)
