# SXP Reference

Errors | General

#### Description

On error, most SXP interface functions output a Sablotron error message and return an error code which can be passed to functions like `SablotGetErrorMsg` (declared in `sablot.h`).

In the callbacks, in contrast, error handling has been kept to a minimum. Typically, in case of an error, a callback just returns a special value such as NULL.
