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. |
e31b636d UH |
53 | * |
54 | * The error codes are globally unique in libsigrok, i.e. if one of the | |

55 | * libsigrok functions returns a "malloc error" it must be exactly the same |
56 | * return value as used by all other functions to indicate "malloc error". | |

57 | * There must be no functions which indicate two different errors via the |
58 | * same return code. | |

3c0839d5 | 61 | * or reused for different errors later. You can only add new entries and |
