Suspends the calling process until delivery of a signal whose action is either to execute a signal-catching function or to terminate the process.
#include <unistd.h> int pause (void);
If the action is to terminate the process, pause does not return.
If the action is to execute a signal-catching function, pause returns after the signal-catching function returns.
| Since the pause function suspends process execution indefinitely unless interrupted by a signal, there is no successful completion return value. | |
| -1 | In cases where pause returns, the return value is -1, and errno is set to EINTR. |
