Chapter 29
| 29.1 | This flag indicates that the jump buffer has been set by sigsetjmp (Figure 29.10). While the flag may seem superfluous, there is a chance that the signal can be delivered after the signal handler is established, but before the call to sigsetjmp. Even if the program doesn't cause the signal to be generated, signals can be generated in other ways, such as with the kill command. |
