* Status/error codes returned by libsigrokdecode functions.
*
* All possible return codes of libsigrokdecode functions must be listed here.
* Functions should never return hardcoded numbers as status, but rather
* use these #defines instead. All error codes are negative numbers.
*
* The error codes are globally unique in libsigrokdecode, i.e. if one of the
* libsigrokdecode functions returns a "malloc error" it must be exactly the
* same return value as used by all other functions to indicate "malloc error".
* There must be no functions which indicate two different errors via the
* same return code.
*
* Also, for compatibility reasons, no defined return codes are ever removed
* or reused for different #defines later. You can only add new #defines and
* return codes, but never remove or redefine existing ones.
