View Ref-File5.21.26  struct sigaction                                          TOS

This structure is defined as follows:

struct sigaction
{
   void cdecl (*sa_handler)(int32_t sig);
   int32_t    sa_mask;
   int16_t    sa_flags;
};

Note: The component sa_handler can assume various values here. A value 
of 0 means default signal-handling by the system, with a value of 1 
the signal will be ignored; any other value will be interpreted as the 
address of a signal handling routine, which is then called.

The component sa_mask contains additionally (to the signal currently 
being processed) the signals to be masked during the signal handling. 
In that case mask = oldmask+(1<<sig)+sa_mask). With sa_flags one can 
influence the behaviour of a signal further. A value of 1 for sa_flags 
means in MiNT that the signal SIGCHLD is triggered only on termination 
and not on stopping the child; other values for sa_flags are not yet 
defined at the present time.
