| Synopsis: | The #error directive should be used with caution. |
| Language: | C |
| Severity Level: | 5 |
| Category: | PREPROCESSING |
| Description: |
Its effect can be achieved by the following: Example:error: This should not happen instead of Example:#error: This should not happen Although both methods will cause an error to be reported by the C compiler, the second form can 'choke' a pre-ANSI preprocessor that doesn't recognise the directive even when the directive is skipped as part of a #if group. The first form will always get through a preprocessor correctly. |
