38 | * This is the only file that libsigrok users (frontends) are supposed to | |
39 | * use and \#include. There are other header files which get installed with | |
40 | * libsigrok, but those are not meant to be used directly by frontends. | |
41 | * | |

50 | * All possible return codes of libsigrok functions must be listed here. | |
51 | * Functions should never return hardcoded numbers as status, but rather | |
52 | * use these enum values. All error codes are negative numbers. | |
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. | |
59 | * | |
60 | * Also, for compatibility reasons, no defined return codes are ever removed | |
61 | * or reused for different errors later. You can only add new entries and | |
62 | * return codes, but never remove or redefine existing ones. | |
