15 The pause() function suspends the calling process until it receives a
16 signal. The signal must be one that is not currently set to be ignored
17 by the calling process.

19
20 If the signal causes termination of the calling process, pause() does
21 not return.
22
23
24 If the signal is caught by the calling process and control is returned
25 from the signal-catching function (see signal(3C)), the calling process
26 resumes execution from the point of suspension.
27
29 Since pause() suspends thread execution indefinitely unless inter‐
30 rupted by a signal, there is no successful completion return value. If
31 interrupted, it returns −1 and sets errno to indicate the error.
32
34 The pause() function will fail if:
35
36 EINTR A signal is caught by the calling process and control is
37 returned from the signal-catching function.
