NAME
pause - suspend process until signal SYNOPSIS
DESCRIPTION
suspends the calling process until it receives a signal. The signal must be one that is not currently set to be ignored or blocked (masked) by the calling process. If the signal causes termination of the calling process, does not return. If the signal is by the calling process and control is returned from the signal-catching function (see signal(5)), the calling process resumes execution from the point of suspension; with a return value of -1 from and set to APPLICATION USAGE
Threads Considerations Signal dispositions (such as catch/default/ignore) are shared by all threads in the process and blocked signal masks are maintained by each thread. Therefore, the signals being waited for should not be ignored by the process or blocked by the calling thread. will suspend only the calling thread until it receives a signal. If other threads in the process do not block the signal, the signal may be delivered to another thread in the process and the thread in may continue waiting. For this reason, the use of is recommended instead of for multi-threaded applications. For more information regarding signals and threads, refer to signal(5). SEE ALSO

NAME
pause - suspend process until signal SYNOPSIS
#include <unistd.h> int pause(void); DESCRIPTION
The pause() function suspends the calling process until it receives a signal. The signal must be one that is not currently set to be ignored by the calling process. If the signal causes termination of the calling process, pause() does not return. If the signal is caught by the calling process and control is returned from the signal-catching function (see signal(3C)), the calling process resumes execution from the point of suspension. RETURN VALUES
Since pause() suspends thread execution indefinitely unless interrupted by a signal, there is no successful completion return value. If interrupted, it returns -1 and sets errno to indicate the error. ERRORS
The pause() function will fail if: EINTR A signal is caught by the calling process and control is returned from the signal-catching function. ATTRIBUTES
