35 | * Status/error codes returned by libsigrok functions. | |
36 | * | |
37 | * All possible return codes of libsigrok functions must be listed here. | |
38 | * Functions should never return hardcoded numbers as status, but rather | |
39 | * use these #defines instead. All error codes are negative numbers. | |
40 | * | |
41 | * The error codes are globally unique in libsigrok, i.e. if one of the | |
2b3414a4 UH |
42 | * libsigrok functions returns a "malloc error" it must be exactly the same |
43 | * return value as used by all other functions to indicate "malloc error". | |
e31b636d UH |
44 | * There must be no functions which indicate two different errors via the |
45 | * same return code. | |
46 | * | |
47 | * Also, for compatibility reasons, no defined return codes are ever removed | |
48 | * or reused for different #defines later. You can only add new #defines and | |
49 | * return codes, but never remove or redefine existing ones. | |
