ssignal() Implement Software Signals
#include <signal.h>
int (*ssignal(sig,action))();
int sig; Type of signal
int (*action)(); Action function/Constant
ssignal() is used to establish an action routine for servicing a
signal. Software signals are associated with integers in the range
from 1 to 15. 'sig' is a number identifying the type of signal for
which an action is established. 'action' is either the name of a
user-defined action function or one of the constants SIG_DFL
(default) or SIG_IGN (ignore) (defined in <signal.h>). If the action
function has been established for 'sig', then that action is reset to
SIG_DFL, and the action function is entered with 'sig'.
Returns: The action previously established or SIG_DFL, if the
signal number is illegal.
