50 | * All possible return codes of libsigrok functions must be listed here. |
51 | * Functions should never return hardcoded numbers as status, but rather | |
3c0839d5 | 52 | * use these enum values. All error codes are negative numbers. |

54 | * The error codes are globally unique in libsigrok, i.e. if one of the | |
