1# Error YAML 2 3D-Bus errors can be defined by creating a YAML file to describe the errors. From 4this YAML file, both documentation and binding code may be generated. The 5generated bindings are C++ exception types corresponding to the D-Bus error 6name. Ex. `org.freedesktop.Example.Error.SomeError` will create a generated 7exception type of `sdbusplus::error::org::freedesktop::example::SomeError` which 8may be thrown or caught as appropriate. If the error is thrown from an interface 9method which has specified it may return that error, then the bindings will 10generate a catch clause that returns a D-Bus error like 11"org.freedesktop.Example.Error.SomeError" to the method caller. 12 13The error YAML is simply a list of `name` along with optional `description` and 14`errno` properties. Example: 15 16```yaml 17- name: SomeError 18- name: AnotherError 19 description: > 20 This is another error. 21 errno: E2BIG 22``` 23
