NAME

pause −  Suspends a process until a signal is received

LIBRARY

Standard C Library (libc.a)

SYNOPSIS

int pause( void );

DESCRIPTION

The pause() function suspends the calling process until it receives a signal whose action is either to execute a signal-catching function or terminate the process.  The signal must not be one that is not acknowledged by the calling process.  The pause() function does not affect the action taken when a signal is received. 

The pause() function, which suspends the calling process until the request is completed, is redefined so that only the calling thread is suspended. 

NOTES

The pause() function is not supported for multi-threaded applications. 

AES Support Level:
Full use

RETURN VALUES

When the received signal causes the calling process to end, the pause() function does not return. 

When the signal is caught by the calling process and control is returned from the signal-catching function, the calling process resumes execution from the point of suspension, and the pause() function returns a value of -1 and sets errno to the value [EINTR]. 

ERRORS

If the pause() function fails, errno may be set to the following value:

[EINTR]The signal is caught by the calling process and control is returned from the signal-catching function.
