|

|
| |
|
39 |
__sleep()__ may be implemented using __SIGALRM__; |
| |
|
40 |
mixing calls to __alarm()__ and __sleep()__ is a bad |
| |
|
41 |
idea. |
| |
|
42 |
|
| |
|
43 |
|
| |
|
44 |
Using __longjmp()__ from a signal handler or modifying |
| |
|
45 |
the handling of __SIGALRM__ while sleeping will cause |
| |
|
46 |
undefined results. |
