| Synopsis: | The signal handling routine signal and the non-specific jump functions setjmp and longjmp shall not be used without specific sign-off according to local procedures. |
| Language: | C |
| Severity Level: | 1 |
| Category: | RESTRICTIONS ON SPECIFIC FUNCTIONS |
| Description: |
| The use of any of these facilities leads to some form of undefined or implementation defined behaviour and many subtle run-time problems can arise. If it is felt that the application absolutely must use this functionality, a wrapper function must be written and its use formally justified by the project manager. |
