| 18 | .SH DESCRIPTION
|
|---|
| 19 | The current process is suspended from execution for the number
|
|---|
| 20 | of seconds specified by the argument.
|
|---|
| 21 | .PP
|
|---|
| 22 | The routine is implemented by setting an alarm timer
|
|---|
| 23 | and pausing until it occurs.
|
|---|
| 24 | The previous state of this timer is saved and restored.
|
|---|
| 25 | If the sleep time exceeds the time to the expiration of the
|
|---|
| 26 | previous timer,
|
|---|
| 27 | the process sleeps only until the signal would have occurred, and the
|
|---|
| 28 | signal is sent 1 second later.
