| * Some code space can be saved by disabling the error |
| * messages if not used. |
| * |
| * PB_SET_ERROR() sets the error message if none has been set yet. |
| * msg must be a constant string literal. |
| * PB_GET_ERROR() always returns a pointer to a string. |
| * PB_RETURN_ERROR() sets the error and returns false from current |
| * function. |
