signal
SIGNAL(3F)SIGNAL(3F)NAME
signal - change the action for a signal
SYNOPSIS
integer function signal(signum, proc, flag)
integer signum, flag
external proc
DESCRIPTION
When a process incurs a signal (see signal(3C)) the default action is usually to clean up and abort. The user may choose to write an
alternative signal handling routine. A call to signal is the way this alternate action is specified to the system.
Signum is the signal number (see signal(3C)). If flag is negative, then proc must be the name of the user signal handling routine. If
flag is zero or positive, then proc is ignored and the value of flag is passed to the system as the signal action definition. In particu-
lar, this is how previously saved signal actions can be restored. Two possible values for flag have specific meanings: 0 means "use the
default action" (See NOTES below), 1 means "ignore this signal".
A positive returned value is the previous action definition. A value greater than 1 is the address of a routine that was to have been
called on occurrence of the given signal. The returned value can be used in subsequent calls to signal in order to restore a previous
action definition. A negative returned value is the negation of a system error code. (See perror(3F))
FILES
/usr/lib/libU77.a
SEE ALSO signal(3C), kill(3F), kill(1)NOTES
f77 arranges to trap certain signals when a process is started. The only way to restore the default f77 action is to save the returned
value from the first call to signal.
If the user signal handler is called, it will be passed the signal number as an integer argument.
