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