<h2>Signals APIs</h2>
|
|
|
|
<p>Signal APIs can be used to manipulate signals in a threaded process. Signals
|
|
can be sent to individual threads, the signal mask of a thread can be changed.
|
|
When a signal is sent to a thread, the actions associated with the signal (such
|
|
as stopping, continuing or terminating) <strong>never</strong> affect only the
|
|
thread, all signal actions are defined to affect the process. When a signal
|
|
handler is called, it is called in the thread that the signal was delivered
|
|
to.</p>
|
|
|
|
<p>Using signals correctly in a multithreaded process can be difficult. The
|
|
recommended way to handle signals in a multithreaded process is to mask off all
|
|
signals in all threads, then use the signals sigwait() API in a single thread
|
|
to wait for any signal to be delivered to the process.</p>
|
|
|
|
<p>For information about the examples included with the APIs, see the <a href=
|
|
