| 30 | @brief |
| 31 | General error codes. |
| 32 | |
| 33 | Many functions, most of them dating from older liblttng-ctl versions, |
| 34 | return this type (or an \c int value which is equal to the negation of |
| 35 | one of those enumerators). |
| 36 | |
| 37 | Not all error codes are relevant to a given function: this API |
| 38 | documentation makes an effort to document the most relevant status codes |
| 39 | for each function. This is not always possible, however, as LTTng is |
| 40 | made of multiple interacting components (tracers, consumer daemons, |
| 41 | session daemons, and the rest); those error codes can move from one to |
| 42 | another and the possible error codes of a given liblttng-ctl function |
| 43 | can change from version to version. |
| 44 | |
| 45 | @sa lttng_strerror() -- |
| 46 | Returns a human-readable message for a general error code, positive |
| 47 | or negative. |
