This is the function pointer type for error callbacks. An error callback function has the following signature: @code void callback_name(int error_code, const char* description) @endcode
@param[in] error_code An [error code](@ref errors). Future releases may add more error codes. @param[in] description A UTF-8 encoded string describing the error.
@pointer_lifetime The error description string is valid until the callback function returns.
